After updating my system to a 17.1 profile, gcc 9.1 w/PGO+LTO failed to compile.  The same package with the same settings compiled fine after the last revbump recently.

emerge --info:

Is this failure reproducible for you exactly in the same form? I tried to build gc with your CFLAGS/CXXFLAGS/USE flags and did not get any errors.
