In case you've got nothing else left to do.. ;)
The ghc command which perfectly repeatable kills gcc:

The (naively) relevant part of the generated HC-file appears to
be the next "function" (with some code which doesn't seem to
matter for the crash removed). I have no idea whether this is of any
help for nailing this kind of nastiness down, so I'm not going to
spend more of my night on it ;)
I did attach the complete failing HC-file.
Greetings,
