Okay, I looked at that page. However, Cygwin's dumper requires you to know
the Windows PID of the process to dump. Clearly it is intended for a
long-running process such as a server process, which you can force to core
dump, as if by "/bin/kill -SIGSEGV pid"; it is not suitable for a process
that gets a segmentation violation for internal reasons. In any case, when
building, I have no idea of the pid of the process which is dumping; it
starts up and then dumps immediately.

The Penguin shall hunt and devour all that is crufty, gnarly and
bogacious; all code which wriggles like spaghetti, or is infested with
blighting creatures, or is bound by grave and perilous Licences shall it
capture. And in capturing shall it replicate, and in replicating shall
it document, and in documentation shall it bring freedom, serenity and
most cool froodiness to the earth and all who code therein. --Gospel of Tux
