I can confirm that `-O3` option is what causes an error; the emerge finishes fine with `-O2`. Probably a GCC issue.
(In reply to comment #1) > I can confirm that `-O3` option is what causes an error; the emerge finishes > fine with `-O2`. Probably a GCC issue. Yup, with -O2 it works. Should this bug be closed or marked as a GCC one? (There seem to be lots of -Ox related GCC bugs reported on bugzilla.)

Not necesarily a gcc bug though. The crash happens in scheme_apply which does a lot of error-prone stuff. This could easily be a buffer-overflow that only shows with optimization enabled.

There's no package named dev-scheme/drscheme, which is why I couldn't find this bug (was it renamed?). Please change the summary :) BTW, the segfault still occurs with the latest version - 4.1.4.
yes, it was renamed. The segfault is different, but I'm guessing it's again because of -O3. I'll talk to upstream about it and am open to suggestions.

Still happens in 4.1.5 (fail with -O3, win with -O2).
I spoke to upstream and I think they fixed this in 4.2. Can someone confirm that please?

Thanks.
