Free:d memory was being used. As I can't reproduce the bug could you run with
it for a while and see if it fixed? The fix is checked in in the emacs-24
branch. I guess it will propagate to the trunk.
After much debugging I think the stack corruption is partly a gdb-bug.
Stepping through the code shows different values for f, but if I print out the
value at the end of the function, it prints the correct value, but not what GDB
prints.
Stack corruption could have happend before, when free:d memory was used though.
