segfault with POST

Hello.

We're currenty experiencing a strange segfault in Mandriva Cooker (the 
development branch) with the latest apache-2.2.17, gcc-4.5.1 and all that.

Compiling apache using "-DDEBUG=1 -DAPR_BUCKET_DEBUG=1 -DAPR_RING_DEBUG=1" or 
without "-fomit-frame-pointer" makes the segfault go away. This seems to 
happen on 32bit cooker only.

More info here:

A possible related issue in WebDAV:

Sounds like an over-aggressive optimization on gcc's part?
