It might that the gdbtk code you are using is not matching the
breakpoint handling code in the underlying Codesourcery gdb.

I don't believe (from my stomach) that the problem here comes
from insight itself. Stack unwinding is done using gdb's
facilities. Have you tried a commandline mingw gdb
(built from the very same code base) and did you issue a
"bt" command there. Do you see than a correct stack dump?
Or have you tried doing a "bt" in insight's console? Is
the stackdump there correct than?
