5.2 RC2: Semi-deterministic gcc segfault during buildworld

Thanks a lot for responding!

Unfortunately this does not seem to be the cause in this case. /etc/make.conf 
does not contain any modifications to gcc optimization parameters, and indeed 
gcc is invoked with only '-O' when compiling.

It's more or less a fresh install; I haven't touched make.conf.
