This is related to #5649, although a different combination of options
produces this bug.

/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.
