fork and Unix signals
-Status: Open
+Status: Feedback
Type: Bug

PHP Version: 5.3.2
New Comment:
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.

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?

Can you try to generate a coredump and use it later to get a bt:

just ran it under gdb, it fails as expected, but as it's not
segfaulting, no backtrace can be made.

PHP itself doesn't crash, the error is not fatal - and how do I make a
gdb backtrace on a forked process, anyway?

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
