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.
