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?

I might already have found the specific cause.

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.

Cheers,
Andreas

Hello,

I'm fine with reverting for now. 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.

Cheers,
