Comment (by pbruin):
I found a patch that I think has the same effect as the workaround in
comment:22. I don't have a sourceforge account, so here it is in case
there are any Maxima experts here who want to check it and (if it is any
good) maybe forward it to the Maxima bug tracking system:

I'll try to see if upgrading to 5.33.0 gives any further unexpected
problems.
