Operating system: Linux 2.4.16
PHP version: 4.1.0
PHP Bug Type: Apache2 related
Bug description: Degmentation fault
It's very hard to tell why this happens, because it only does occationally.
I've included a back trace:
I'm running Apache 2.0.28 in prefork mode. As you can see the error occurs
when I'm just trying to write something to the client. It doesn't seem to
be associated with any particular operation. If I reload the same page 10
times, only 0-2 segfaults occur. However, most of the time there simply is
no PHP output on the pages, but there are no segfaults either.
