   GCC 8.2.1 from devtoolset-8: Segfaults
   GCC 7.3.1 from devtoolset-7: Segfaults
   GCC 6.3.1 from devtoolset-6: Segfaults
   GCC 5.3.1 from devtoolset-4: NO Segfault
   GCC 4.8.5 from EL7.6: NO Segfault
   
   Quite interesting results there, I did not expect that.
   Not sure whether this goes for those GCC versions in general, or whether the 
devtoolset modifications are somehow causing problems here (For example they 
always include some parts of libstdc++ statically, to remain compatible with 
the old libstdc++ in the distro proper).
   
   Whether this needs a fix in GCC or in devtoolset, or can be fixed in 
pagespeed using a workaround is not something I can help with I am afraid. But 
I hope someone will be able to build upon this report.
   I will help provide further details if I can, but please note that each 
iteration takes me 15min of build-time.
