Mandrake is not compatible with memprof - I don't know why,
but I've had several reports of this.

The problem is that memory-interception library which is loaded
into the child process segfaults when trying to do a backtrace.
The one possibility that occurs to me is that some library - 
perhaps even libc, was compiled with -fomit-frame-pointer.
