PHP Bug Type: Reproducible crash
Bug description: Crash in _zval_ptr_dtor()
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.
