OK, setting SplitObjs = NO got it past that compilation error, so
it must be the splitter script as you suggest. Unfortunately, there
was a subsequent error: the stage1 compiler crashed building stage 2:

I'll be happy to do any other investigation anyone suggests.

Ok, then we'll have to dig further. Suggestions:
- turn off splitting: add SplitObjs=NO to mk/build/mk. If this
makes
the error go away, then the problem is likely in the split script
(driver/split/ghc-split.lprl).
- If the error is still there without splitting, then compile the
module with -keep-tmp-files, and take a look at the .s and .raw_s
files to see where the local symbol is coming from.
Cheers,
Simon
