Segmentation fault (core dumped) in PHP -

Segmentation fault (core dumped) in PHP -

ok, i'm running php app on command line on ubuntu, , ends "segmentation fault (core dumped)".

how go here debug it? i'm pretty sure there no memory leak checked get_memory_usage().

edit: alright, explained brendan , ulricht, tried gdb. that's not environment @ sorry oncoming newbie questions.

i ran code under gdb , got segfault. here first 22 lines.

(gdb) bt #0 0x00000000006f5d36 in ?? () #1 0x00000000006f7625 in ??

according https://bugs.php.net/bugs-generating-backtrace.php, should "execute" calls, instead have "execute_ex". same thing?

the next command anyway not homecoming function name (after having done frame 6):

print (char *)(executor_globals.function_state_ptr->function)->common.function_name effort extract component of value not structure.

edit2: i'd appreciate knowing why downvote. think it's valid question , haven't found similar 1 php. if there you're free comment.

there several things pinpoint error, first run executable in gdb:

> gdb /usr/bin/php .... (gdb) run path/to/script

note can load dumped core gdb. other tools finding out cause issue strace , valgrind.
