[Jool-list] HELP: My custom build doesn't work exactly

Fri Dec 6 11:18:44 CST 2019

Replicated in a fully 64-bit system by simply adding -m32 to both
CFLAGS and LDFLAGS. (`make CFLAGS=-m32 LDFLAGS=-m32`)
This is a bug. I'd be thankful if you could submit it to the issue tracker.
Regardless, I will be patching it right now. In a few hours I should
have an estimate on how long it's going to take.
