A negative breakpoint means internal to gdb (like a breakpoint gdb sets
for stepping). So when you press F8 gdb apparently can't get the correct
location where the step should end.
Are you sure your app (and package that has debug info) are compiled:
- with either -O0 or -O1 (no other optimization enabled)
- your app is NOT smartlinked
