--- Comment #15 from acsawdey at gcc dot gnu.org --- The build succeeds with -fno-split-stack. Turned out that willow2 had glibc-2.17 so split-stack was disabled and genoa has 2.23 which enables it. So this issue has something to with compiling for split-stack that is perhaps causing memory corruption within the compiler.
