Okay, that's the problem. You told Guile that the C string was encoded
in UTF-8, but actually it was encoded in Latin-1:

That 169 on the second-to-the-last line is 0xA9, which is the Latin-1
encoding for the copyright symbol. It is not legal as a bare character
in UTF-8. The correct UTF-8 encoding for that symbol is 0xC2 0xA9.
As for the SIGSEGV, that's probably a bug in the backtrace printer for
Guile. Sorry about that. Thanks for the info.
