I found the reason to be combination of -std=c99 with features from
POSIX, so another macro should be defined instead, please try with
these changes:

diff --git a/src/Makefile.config b/src/Makefile.config

With this I can't reproduce any segfaults. Please report if there're
any other problems left.
