All of Gentoo, Debian and Fedora use included Boehm-Weiser garbage
collector.  From config log:

configure: Configuring included Boehm GC library:
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
checking GC version numbers... major=6 minor=8

So, it seem to be version 6.8.

AFAICS Fedora problem is triggered by security measures: when
I did (as a root):

echo 0 > /proc/sys/kernel/randomize_va_space

echo 0 > /proc/sys/kernel/exec-shield 

then build went fine.
