Ok, I'm running a PHP app on command line on Ubuntu, and it ends with "Segmentation fault (core dumped)".
How do I go from here to debug it? I'm pretty sure there is no memory leak as I checked it already with get_memory_usage().
Edit: Alright, as explained by Brendan and Ulricht, I tried gdb. That's not my environment at all so sorry for the oncoming newbie questions.
I ran my code under gdb and got the segfault. Here are the first 22 lines.
(gdb) bt

According to https://bugs.php.net/bugs-generating-backtrace.php, I should get "execute" calls, instead I have "execute_ex". Same thing?
The following command anyway does not return the function name (after having done frame 6):
print (char *)(executor_globals.function_state_ptr->function)->common.function_name
Attempt to extract a component of a value that is not a structure.
Edit2: I'd appreciate knowing why the downvote. I think it's a valid question and I haven't found a similar one for PHP. If there is then you're free to comment.
There are several things to pinpoint the error, but the first is to run the executable in gdb:
> gdb /usr/bin/php
....
(gdb) run path/to/script
Note that you can also load the dumped core into gdb. Other tools for finding out what could cause the issue are strace and valgrind.

Backup failed because: The dump process failed with exitcode 1 : General error : '"mysqldump"' is not recognized as an internal or external command,
operable program or batch file.
I searched for solutions and found the code below:
'connections' => [
'mysql' => [
'driver' => 'mysql'
...,
'dump' => [
'dump_binary_path' => '/path/to/the/binary', // only the path, so without `mysqldump` or `pg_dump`
'use_single_transaction',
'timeout' => 60 * 5, // 5 minute timeout
'exclude_tables' =>['table1', 'table2'],`enter code here`
'add_extra_option' =>'--optionname=optionvalue',
]
],
But still I'm getting same error... I tried more than 100times, still nothing.
So any one who gone through this problem or any body who knows how to solve this please help me out.
in the code you found, where says:
'dump_binary_path' => '/path/to/the/binary',
Change to:
'dump_binary_path' => 'C:\xampp\mysql\bin',
Next time, look to the errors because int his case, the problem is well described!
Regards
Now you also need to comment this line:
//'add_extra_option' =>'--optionname=optionvalue',
working for me.

I have a production site using Database from an Amazon Server, I have two more sites on the same server and both of them connects without issues.
On this particular site the connection to mysql is not working, I thought that the env file was missing or not being see by the laravel app but is not the case, when I run php artisan tinker and try any command it works:
DB::table('categories')->get();
=> Illuminate\Support\Collection {#842
all: [
{#828
+"id": 1,
+"parent_id": null,
+"order": 1,
+"name": "Noticias",
+"slug": "noticias",
+"created_at": "2018-01-09 19:26:32",
+"updated_at": "2018-01-09 19:26:32",
},
],
}
The App::environment() method also works:
>>> App::environment();
=> "production"
The env files clearly says APP_DEBUG=false but it is returning a lot of debug, it is like the webserver is not reading the env file besides the artisan is.
This is driving me crazy because it started failing by itself, nothing was changed on the server or the code, it's the only project that is failing.
What else can I check?

You should verify if you have bootstrap/cache/config.php file. If yes, it means, your config is cached. Than you can run:
php artisan config:cache
to refresh config and sync data you have set in .env or
php artisan config:clear
if you don't want to use cached config (keep in mind it's recommended to cache config on production)
The solution for me was to restart the laravel development server, ie: run php artisan serve again.
I had changed the db config after I had originally run the dev server.
I had a similar problem, I installed php7.2-mysql after I installed everything else. Tinker was working perfectly but my application would not connect.
I spent 2 hours trying to debug until a simple apache restart did the trick.
The problem is that mysql's root user can't be used anymore, since mysql v5.7. More about this here.
I have several crons running at various times every day. Occasionally, one or another will get 'stuck' and its process will never die. This isn't consistent, but after a change in a function in a different file which several of the crons access, there's been a marked increase in the number of times. Not always to the same file, not always to the same time, and running the files manually works fine.
My questions:
If I modify this external file, the running cron should pick up the change, right? (Tried and it isn't working, so either it doesn't, or it didn't get to that point in my code, which brings me to my second question:)
How can I print a stack trace of the running cron in order to see where it gets stuck? Running on Linux, Centos version 7
Edit: pstack gives me main() - how can I get farther in than that?

Thanks for any help!
If any of the crons are leaving the file open then this might be the cause when a concurrent access attempt is made to the same file by different cron instances. You could write a small shell script to execute the code file preceded by something like
$ok = `lsof | grep -c <filename>`
if($ok != "0")
then sleep 5
