php library

[Christophe Moins <christophe.moins@ego-gw.it>]

Hello,

We have tried to use apache 2.0.40 and apache 2.2.2 with php4.2.x and 
php 5.1.x in various combinations with the php_epics library for php. 
Our test platform is RH9 with a 2.4 kernel. However, everytime we 
execute a php script that calls the ca_get , ca_put, etc.. routines, the 
apache server reports a segmentation fault as follows

[Tue Jun 06 14:23:13 2006] [notice] child pid 5939 exit signal 
Segmentation fault (11)
[Tue Jun 06 14:24:13 2006] [notice] child pid 5937 exit signal 
Segmentation fault (11)
[Tue Jun 06 14:25:13 2006] [notice] child pid 5936 exit signal 
Segmentation fault (11)
[Tue Jun 06 14:26:14 2006] [notice] child pid 5933 exit signal 
Segmentation fault (11)
[Tue Jun 06 14:27:19 2006] [notice] child pid 6115 exit signal 
Segmentation fault (11)
[Tue Jun 06 14:27:26 2006] [notice] child pid 6089 exit signal 
Segmentation fault (11)

Unfortunately, sometimes, one of the children of the main apache process 
fails resulting in a TRACED (T) flag in the process list as viewed from 
`ps aux`.  We are not tracing anything. This child cannot be killed and 
binds itself to the httpd tcp socket meaning that we cannot restart the 
webserver.

Have you seen this before? Or, perhaps, can you suggest some way to 
debug this. We are unable to debug apache using `strace` or `gdb` giving 
the "Operation not permitted message", even as root.

Your help in this matter would be greatly appreciated.
