I have been trying to use valgrind with Fedora 15 and I find that I am not getting the complete backtrace information. Let me provide a simple example:
Valgrind works fine for me:

Compile with:
gcc -o -g test test.c
This won't generally run successfully - you're asking gcc to compile "test" and "test.c" and put the output in a file named "-g". Depending on what "test" is this will most likely fail in different (weird!) ways.
You probably want something like:
gcc -o test -g test.c
Is it possible you had an old version of "test" lying around and it lacks debug symbols?
