So: SIGSEGV (signal 11)

"uname -apKU" output from the building environment?

Commit identification for the /usr/src/ for stable/13
that is being built?

Any console messages? dmesg -a output of interest?
/var/log/messasges content of interest?

Any messages of interest somewhat earlier in the
buildworld.log ?

Does the problem repeat via using the files:

/tmp/gmock-all-836ef8.cpp
/tmp/gmock-all-836ef8.sh

on that RPi3? Elsewhere that has more resources, such
as more RAM?
