Comment (by Phyx-):

 Hi Simon,

 I started looking last weekend and will continue coming one. Luckily the
 byte code interpreter seems to crash already at the first BCO it's trying
 to interpret. Just working my way through the scheduler to try to figure
 out what it was supposed to be.

 If I don't find the cause this weekend I'll be sure to ask for help. I
 only have time to look at GHC in the weekends so don't want to hold things
 up on me :)
