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.

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:
