Comment(by erikd):
It seems the code that's needed looks something like:
{{{
toEntryLbl (CmmLabel m str CmmCode) = ?????
}}}
Replacing ????? with the obvious `CmmLabel m str CmmCode` results in the
following when the stage2 compiler is run"
{{{
ghc-stage2: internal error: scavenge_stack: weird activation record found
on stack: 65310
(GHC version 7.7.20121022 for arm_unknown_linux)
Please report this as a GHC bug:

}}}
