Well, that's not exactly what happened. The branch for what would eventually become fedora 32 just inherited a pre-release GCC version, because that's what was on the master branch / in rawhide at the time. I think we just jad a bit of "bad luck" this time round - the exact build that was used a period of time (including the mass rebuild, I think) seems to have produced buggy code in some circumstances. If those issues had been compile time errors instead of runtime errors, they would've been caught pretty quickly, but alas ...
