This is a known limitation of Win31, which cannot handle 
correct the breakpoints (software breakpointts). You
should use either hardware breakpoints (hbreak in gdb),
use RHGDB (which recognises that you are running under
Win31 and uses automaticaly hardware breakpoints) or
run under plain DOS.

And make sure you have read the FAQ, where this is described
in section 12.9 the last paragraph.
