I do indeed have SplitObs=YES in my validate.mk. In the past at least, that made binaries quite a bit smaller. Happy to change it to SplitSections=YES if that is more kosher these days?

It seems with split sections we generate a dummy CmmProc, which has as entry label > error (split_sections_entry) My patch likely introduces strictness on that field where it was lazy before. If this is the cause I expect to have a patch up in a hour or two and will merge it after it validates.

But could you give me a way to reproduce this error? I've not seen crashes on either linux and windows in various configs. I suspect that Simon is building with SplitObjects enabled. To be honest, I would really like to remove this feature; SplitSections is better in nearly every regard. However, we have been stalled since SplitSections doesn't quite work yet on Windows (or, IIRC, the toolchain is prohibitively slow when it's used). I believe Tamar was working on fixing this.
