I don't think GDB is the culprit here: it supported stabs since v4.18,
perhaps even before that.  I'm quite sure stabs work for me with GCC
3.0.2 as well, but I cannot test that at the moment.

Do -ggdb and -gstabs give you the same results?

If nothing else helps, could you make the offending program (source
and unstripped binary) available for download somewhere, so I could
look into it?
