So it seems that either there's a bug in clang, or a bug in guile that
causes problems when compiled with clang (which has different aggressive
optimizations than gcc).  Based on anecdotes from many other packages,
it seems more likely than not that it's a guile bug.

It would be interesting to bisect compilation of guile with 2 compilers,
or to compile with clang with optimization turned way down.
