 Replying to [comment:7 dylukes]:
 > I initially thought this might only affect 64bit programs compiled by
 64bit GHC... but it seems in (rarer) cases it may affect 32bit programs...
 Though, that may be another issue entirely.

 Turns out it does only affect 64bit programs. This case was where I was
 building a 64bit executable with 32bit GHC during the bootstrapping
 process of building GHC. It's just 64bit.
