Please don't use too much time on this if this stack trace does not
say something very clear. It dawns on me that maybe I should try a more
straight version. I do not use a patched glibc coming with Gentoo, I
use a straight one from the Glibc-dev-team and I have excluded localization
so that shell and glibc is clean ascii.
Some programs do not like that solution (others do).
But of course the stack trace shows that we were coming from
something scm_dapply() in libguile, so libguile could be the
culprit, too, coudn't it?
Thank you for fast reaction!! Now don't spoil your night's sleep,
I can wait until much later:-)
