Assembler error message in GHC 7.2.2
This is related to #5649 (closed), although a different combination of options produces this bug.
ghc -O Bug.hs [1 of 1] Compiling Bug ( Bug.hs, Bug.o ) /tmp/ghc23962_0/ghc23962_0.s: Assembler messages:
/tmp/ghc23962_0/ghc23962_0.s:2849:0:

/tmp/ghc23962_0/ghc23962_0.s:3291:0:

I realize the bug is not present in 7.4, but I am using 7.2.2 in a production system and this is messing things up. Is there any chance the fix for this bug could be backported to 7.2.2?
Further info: the attached file seems pretty minimal in producing this bug. For example, if using up to 8-tuples, the bug is not present; it is present if 9-tuples and 10-tuples are used. The -O option is necessary; neither -O0 nor -O2 produces the bug.
