Subject: bug#33216: using custom optimization options eats goops object

[Message part 1 (text/plain, inline)]

Hi!

When running `step.scm' (attached) the expected behaviour is exit 0.

Using auto compilation or default optimization options, that's what
happens

--8<---------------cut here---------------start------------->8---
$ rm -f step.go && guile -e '(step)' step.scm 
15:39:41 janneke <at> dundal:~/src/bug-0
--8<---------------cut here---------------end--------------->8---

However, when compiled with a particular set of optimization options
(see attached compile.scm), I get

--8<---------------cut here---------------start------------->8---
$ rm -f step.go && guile -L . -C . compile.scm && guile -L . -C . -e '(step)'

The error message seems to suggest that <node> `one' is now the empty
list.

This is with  Guile 2.2.4 from current Guix master.

Greetings,
janneke
