dumper does not produce core that gdb recognizes?

Ideally, that would be the case.

Unfortunately, for a long time, on x86_64, dumper wasn't working 
correctly, and gdb couldn't read those dumps, and nobody cared enough to 
do anything about it.

This was fixed in gdb-10.1-1 [1] (upstream in gdb 11) and cygwin 3.1.7.

If you choose to use earlier versions on x86_64, it's a known defect 
that it won't work.
