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

Fri Dec 6 10:26:53 CST 2019

I'd say the most likely cause is the 32-bit OS on top of the 64-bit
kernel. I mean I know we're supposed to support it, but I left it out
of the tests because I already had too much on my plate, and then
forgot about it. You're the first person attempting this as far as I
know.

I'll try to replicate it. BRB.
