Ok, --disable-all reminded me that I had an auto-included header on
that web site so the test code wasn't as simple as I thought. Sorry for
the confusion.
I've narrowed down the code which is causing the crash to:
ltrim('/test.php', '/');
and it still crashes with --disable-all
% gcc -v
Using built-in specs.

I don't have access to Solaris 10/64bit, but I can't reproduce the
problem on any other OS I can find around here (Linux, FreeBSD, MacOS,
AIX).
Please try to build it with --disable-all and see if it changes
anything.
What compiler do you use, btw?

Same result with latest 5.2 CVS

Description:
------------
I've compiled PHP 5.2.0 as a replacement for 5.1.6 which is running
fine here. 5.2.0 crashes with any PHP web page.
This is Solaris 10, 64-bit.
I've recompiled without any extensions, same result.
./configure \
--prefix=$DIR \
--with-exec-dir=$DIR/bin \
--with-apxs2=/opt/apache/bin/apxs \
--disable-libgcc \
--disable-libxml \
--disable-dom \
--disable-simplexml \
--disable-xml \
--disable-xmlreader \
--disable-xmlwriter \
--without-pear
Not sure how to debug this further.
Reproduce code:
---------------
<?php print "test"; ?>
Expected result:
----------------
test
Actual result:
--------------
Program terminated with signal 11, Segmentation fault.
