I think this "latest" snapshot is nothing more than a fresh CVS
checkout, so I did the checkout first. ;-)
Same Error:
(gdb) run segfault_mysql_free_result.php
Starting program: /usr/bin/php segfault_mysql_free_result.php
1 GO 2 OK
Program received signal SIGSEGV, Segmentation fault.

After that I tried the "latest" Snapshot:
The same :(

I tried it on another Machine with actual PHP5-CVS Sources, it runs
there. So the Problem must be somewhere in my System libs or something
like that.
I'm using:
Linux 2.6.5
gcc (GCC) 3.3.2 20031218
...for more version-numbers simply ask.
(other machine uses Linux 2.4.*)

Please try using this CVS snapshot:
http://snaps.php.net/php5-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php5-win32-latest.zip

Perhaps the Apache/MySQL-Version helps:
apache-2.0.48-r1
mysql-4.0.18
(both gentoo ebuilds)

Did a complete cleanup on PHP and installed the new Version:
$ rm /usr/bin/php
$ rm /usr/lib/apache2/libphp5.so
$ rm -rf /usr/lib/php
-> CVS checkout (deleted the sourcedir before)
-> newly compiled with options like above
...same error :(

I tried running the code again, but I only get
"Fatal error: Exception thrown without a stack frame in
Unknown on line 0" regardless of unset().
