[Geiser-users] Error while opening MIT/GNU Scheme

[Diogo F. S. Ramos]

When opening MIT/GNU Scheme by M-x run-mit (or by jumping from a source
file using C-c C-z), the following error occurs:

--8<---------------cut here---------------start------------->8---
MIT/GNU Scheme running under GNU/Linux
Type `^C' (control-C) followed by `H' to obtain information about interrupts.

I investigated a little and removing expression
(cref/generate-constructors "geiser" 'ALL) from
`scheme/mit/geiser/compile.scm' solves the problem.  I couldn't figure
out what that expression does, so I'm sure other things break without
it.

I'm using MIT/GNU Scheme version 10.1.5 from Debian Buster and Guile
from master (6db4fb2cd0ca86f27b8e08e15e8493a2d08d48f2).
