Investigation on an i386 host, and then a git bisect suggested that this
might be relevant (i.e. the "bad" commit bisect landed on):
commit d579848cb5d65440af5afd9c8968628665554c22
Fix bug lowering logand/immediate to ulogand/immediate
* module/language/cps/specialize-numbers.scm (logand/immediate): Define
a sigbits handler.
(specialize-operations): Require logand/immediate operand to be u64 to
lower to ulogand/immediate. Shouldn't be necessary but even if only u64
bits are used, negative fixnums will have the sign bit set, which trips
up further unboxed uses which error if the operand to `scm->u64` is
negative.
* module/language/cps/type-fold.scm (rem): Emit logand/immediate.
I also found some other issues I have patches for that I'll propose
separately, e.g. test-hashing needs a 32-bit "expected", etc.
Hope this helps, and happy to assist if I can.
Thanks
