Ok, I had success by removing “-debug” in favour of “-DDEBUG”. After compiling GHC I fired GDB and this is the output:

Maybe it does ring a bell to any of you. In case not, I’m happy to continue digging.
It doesn't ring a bell and I'm not near a computer at the moment, but it sounds like you are hot on the trail; that is a far more tractable error. I'll have a look at the code to see if I can see any obvious things to check when I get back home.
