Summary: Apache Segfault when xdebug.collect_params is ON
Description:
When xdebug.collect_params is OFF, everything works like a charm. Once I
turn it on, all php scripts (except one that execute phpinfo() only) stop
working. In Apache error log I see errors "[notice] child pid XXXXX exit
signal Segmentation fault (11)".

P.S. I'm using PHP 5.0.6-dev (latest CVS) and XDebug from CVS downloaded
today (Oct 14 around 12:30PM -0500)

Hello,

I just committed a "fix" to CVS, can you please verify that this stops the
crash itself? (The parameters will be shown as "???" though, I do need to
look into this a bit better).

Yes, I tested it and it's not segfaulting and all parameters are "???" :)

I think I figured out what is causing this - it might be GCC's over
optimizating something. Which GCC version do you use (gcc --version) and
does it work if you remove the "-O2" from the Makefile before compiling?
