I think the configuration that exhibits this bug is gcc 4.9 with
-fstrict-overflow ("Allow the compiler to assume strict signed overflow
rules"), which is enabled by -O2, -O3 or -Os, and without -fwrapv ("assume that
signed arithmetic [...] wraps around using twos-complement representation").

Distributions typically compile libraries with -O2; that's certainly what
Debian does.
