ID: 51580 User updated by: marco at vmsoft-gbr dot de Reported by: marco at vmsoft-gbr dot de Summary: socket_select randomly crashes when used together with fork and Unix signals -Status: Feedback +Status: Open Type: Bug Package: PCNTL related Operating System: Debian Linux PHP Version: 5.3.2 New Comment: It doesn't crash in the literal sense, as I said before this was a mistake in word choosing. So it's technically something other than a crash, but I dunno how to properly call it. It's a bug, that's the only thing thats sure. Previous Comments: ------------------------------------------------------------------------ [2010-04-17 13:46:57] paj...@php.net If it crashes then linux should be able to generate a core dump file (without gdb). You can then use it to generate a back trace. ------------------------------------------------------------------------ [2010-04-17 13:39:33] marco at vmsoft-gbr dot de Uh, the PHP *process* doesn't crash, so no corefile. Sorry, was bad choice of words by me. Anyway, whatever happens with socket_select there should not happen... but how to backtrace that one without an actual crash? ------------------------------------------------------------------------ [2010-04-17 13:23:08] paj...@php.net Can you try to generate a coredump and use it later to get a bt: http://stackoverflow.com/questions/17965/generate-a-core-dump-in-linux ------------------------------------------------------------------------ [2010-04-17 11:13:18] marco at vmsoft-gbr dot de just ran it under gdb, it fails as expected, but as it's not segfaulting, no backtrace can be made. ------------------------------------------------------------------------ [2010-04-17 11:06:53] marco at vmsoft-gbr dot de PHP itself doesn't crash, the error is not fatal - and how do I make a gdb backtrace on a forked process, anyway? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
