If you program Forth like it's C, and then use a non-optimizing compiler, you're going to have a bad time (e.g. 10/20x slowdowns).

I've written Forth compilers that generated output that was ~25% slower than optimized assembly, without putting that much work into it. There are companies that will sell you a much better compiler [0], at prices even approachable to hobbyists.

FWIW: The URL is being truncated right at the "...for-linux" part. I was mildly surprised.

This particular distribution also ships with GTK+.

That being said, a simple "3 2 1 ?" (I was unsure what word would dump the stack) SIGSEGVs quite consistently.

It's also 32-bit, and the backtrace handler produces "XXXX:XXXX" style addresses (?).

You’re dereferencing an invalid pointer with a variable lookup; try “3 2 1 .s” ... there’re some good ANS Forth gems here [0].
