segmentation faults

[Rodrigo Werneck Silva <ro...@labhpardini.com.br>]

I'm running apache 1.3.22 and seing a lot of segmentation faults in the error_log file like those:
------
[Wed Feb 27 12:56:54 2002] [notice] child pid 23874 exit signal Segmentation fault (11)
[Wed Feb 27 12:56:54 2002] [notice] child pid 23857 exit signal Segmentation fault (11)
[Wed Feb 27 12:56:54 2002] [notice] child pid 23412 exit signal Segmentation fault (11)
------

I've tried to GDBug a lot of httpd processes and could catch the segmentation fault just twice so far.
In the first it was my mod_weblink the module which caused the segfault. In the second mod_php4 was aparently the bad guy.
For the latter, Backtrace follows:

Any hint?
