Comment 1 Jonathan Wakely 2018-09-19 12:54:07 UTC 
This doesn't happen for anybody else using gcc-7.3.1-6.fc27.x86_64 so it suggests a hardware problem or something else wrong on your system.
Comment 2 Marek Polacek 2018-09-19 13:02:58 UTC 
Indeed, please run "rpm -V gcc gcc-c++ libstdc++ libstdc++-devel" to see if that is ok.

I think I had run a verify on libstdc++-devel, since that owns the file in the error message.  But your suggestion reports a fault with /usr/libexec/gcc/x86_64-redhat-linux/7/cc1plus. So, yes, probably a disk problem.  Thank you.
Comment 4 Marek Polacek 2018-09-20 00:55:44 UTC 
Alright, closing then.

A corrupted C++ header should not be able to cause a bus error in the compiler. So it's a problem in the compiler, not the header.

Based on comment 3, the compiler binary (cc1plus) was corrupted.
