I wonder if this is a known problem. Is it an optimized build? If so, it's expected. In general, debugging -gcoff code is fragile, as both GCC, Binutils, and GDB stopped actively using that debug info long ago. So yes, debugging is somewhat a challenge, and expect to have to use stepi frequently because just step won't work, for example.
