Bug description: Segmentation fault - related possibly to error handling functions
I have code that ran fine under 4.3.1 compiled with Apache like so:
'./configure' '--with-openssl' '--enable-memory-limit'
'--with-mysql=/usr/local/mysql' '--with-zlib'
'--with-apache=../apache_1.3.27' '--enable-inline-optimization'
'--with-curl=/usr/local' '--with-mcrypt=/usr/local'
It was compiled the same exact way with 4.3.2 except with a newer version
of curl.
This same code now causes a segmentation fault under 4.3.2:
[Tue Jun 3 21:25:51 2003] [notice] child pid 12107 exit signal
Segmentation fault (11)
The offending code is related to a user defined error handler. My current
workaround: remove the error handling code. I have isolated the problem
to a single file and a function within that file. When I comment out the
code that loads this file and calls that function, the segfaults stop and
the code runs as normal:
//include_once('lib/Error/Handler.php');
//CDS_Error_Handler_Init();
Furthermore, I have to call the function - loading the file alone does not
cause the problem. This error handler is a very old version of our
current one which has changed significantly and has no problems in 4.3.2.
You can find the code here:

I hope this helps - I am in no way put in a bind because of this bug - it
is old code and does nothing for us now. Just hoping to help PHP out in
any way possible. I tried out RC1 on the developemntal servers, but as
it is sometimes, you don't catch the bug until you go to production.
