Crash in PHP 4.3.11 after an extension function ( gcc 4 on Fedora Core 4)

[rgristroph]

I have an extension in C++, which I compile as a module for php 4.3.11.
I am using PHP 4.3.11 on Fedora Core 4, which has gcc 4 instead of gcc
3.2.

Fedora Core 4 normally comes with PHP 5, but I removed it and installed
PHP 4.3.11 from source, so that I didn't have to figure out problems I
had with my extension and php 5.

After a number of calls to my extension, there is one call to function
(which has been called before) in which the code exits my function, and
then crashes inside PHP shortly thereafter. The seg fault is in
php-4.3.11/Zend/zend_execute.c on line 1658, which reads:

EG(current_exec ute_data) = &execute_dat a;

The extension function it is returning from returns a long, not some
fancy php object or reference.

I don't know if anyone on this forum will have any ideas, but if you
have any thoughts at all please offer them.

I am thinking that this might be a result of php being compiled with
gcc4, and the new gcc 4 does something different and exposes some bug
in PHP ? Has anyone seen problems running PHP 4 compiled with gcc 4 ?

Any thoughts at all are appreciated.
