Package: guile-3.0
Version: 3.0.4-1.2
Severity: normal

Hello!

I'm working on updating guile-lib to guile 3.0 and found that one of
the tests doesn't pass. The md5 library appears to be miscompiled.

There's a loop in general-read-string!/partial that never terminates.
Change (+ read 1) to (- read -1) and suddenly it does terminate. The
only way that this makes sense to me is if the loop with (+ read 1) is
miscompiled.

(Unfortunately this workaround isn't enough, there is later a
mysterious stack overflow as well, that wasn't present with Guile
2.2).
