--- Comment #7 from Abrahm Scully <abrahm.scully at gmail dot com> ---
I hit an ICE today that looks like this bug. I attempted to build
gcc-10-20200329 on 32-bit CentOS 6 using g++ 4.4.7-23.el6. I don't see this bug
building gcc-6.3, gcc-7.3, gcc-8.3, or gcc-9-20200118 on the same platform.
I'll dig into the problem more soon...
