AFAIK, the only thing that's cygwin-specific about dumper.exe is to use
cygwin's "just in time" debugging facility so, although dumper.exe
should be able to produce a core file that gdb will understand, I don't
think there's any way to have it called automatically when a SEGV (or
whatever) happens.

Perhaps "gdb --help" would be of some interest to you. It reveals this
option:
gdb --args foo --arg1 --arg2
