Package: guile-1.6
Version: 1.6.8-6
Severity: serious
Tags: patch
Guile 1.6 fails to build with gcc-4.3 on at least powerpc. The
bootstrap guile segfaults at start time. This is the same problem
as guile 1.8 had in #481378. I adapted the upstream change and
tested the resulting patch. The appended version of it covers only
the configure.in, configure needs to be regenerated afterwards,
which conflicts with a patch from the debian patchset.

This should be fixed as of at least 1.6.8-10.
Thanks
