PHP Bug Type: Scripting Engine problem
Bug description: CLI Segfault
Goofing around with shell scripting in PHP, I bumped into this problem. I
scanned the other segfault bugs, but I didn't find one like this.
Additionally, I haven't tried with any nightlies, so sorry, but here we
go.
When running a script with the CLI binary as so:
# php -q < somescript.php
I receive a segfault. This should work as PHP should parse stuff from
stdin, and this is just a pipe. Copying the script to stdin when calling
PHP as
#php -q
I'm able to run the script successfully. Additionally, I can run the
script by doing
# php -q somescript.php
I'm positive that this is because I have PHP reading its pipe from stdin
and then requesting user input from stdin as well. But PHP should die
gracefully and not segfault.
Oh yeah, here's the really strange backtrace

Aha! But before you say "idiot, go email Nick", here's the backtrace with
the loader turned off :P. It just proves that Nick's gotta fix his stuff
also.
