Comment 4 Miroslav Lichvar 2016-02-17 14:41:40 UTC 
It looks like the problem is in scm_to_int64() (libguile/conv-integer.i.c) as it depends on -LLONG_MIN being less than zero, which is undefined behavior and it fails with the new gcc. Adding -fwrapv to the CFLAGS seems to fix it.

Interestingly, the code in guile-2.0.11 looks identical, but the test doesn't fail.
