Correct; the [panic] you noted is actually part of the test; it checks
that returning twice from a callback fails (which _should_ trigger a
panic).  That's why it says "double-return from callback failed as it should."

I agree this is somewhat surprising.

The GCC bug is known; I tried to explain this in the RC announcement
mail.  It will probably disappear with CHICKEN 4.11, if it includes the
new "argvector" branch.  If you would like to run the tests through to
completion on this platform you can try installing the gcc-4.8 package
or clang, and set the C_COMPILER variable to this compiler.

Anyway, thanks for testing, Tim!

Cheers,
Peter
