'-c' is not a valid option for dumper.

Can you point out what documentation mentions that so we can fix it!

It's awkward because a new terminal is started for dumper, which 
disappears almost immediately, but if you add 'pause' at the end of your 
.cmd file, you should see it.

But I think you are overcomplicating things here: 'export 
CYGWIN=error_start=dumper' should work (or even 'error_start=gdb' if 
you're just going to load the core dump into gdb afterwards...)

Cygwin is waiting for the debugger to attach, indefinitely since it 
never happens here.
