A pointer please? I'm not sure how to approach this.

My test.sh is only
x86_64-pc-linux-gnu-g++ -fvisibility-inlines-hidden -Os -pipe
-fomit-frame-pointer -std=c++14 -fPIC -m64 -pthread -finline-functions
-Wno-inline -Wall -fvisibility=hidden -DBOOST_ALL_DYN_LINK=1
-DNDEBUG -c -o instantiate_predef_macros.o
instantiate_predef_macros.pp.cpp > gcc_out.txt 2>&1
grep "stack smashing detected" gcc_out.txt >/dev/null 2>&1
so there isn't much to change. I suppose I could try removing some of
the parameters, but I don't personally understand them well enough to
know if they will affect the outcome. I suppose I could try a manual
creduce on the command line itself :-)
