After upgrading gcc from 10.0.1-0.7.fc32.x86_64 to 10.0.1-0.8.fc33.x86_64 I observe an internal compiler error when building perl-Devel-NYTProf-6.06-8.fc33 package <https://koschei.fedoraproject.org/build/7985159>:

I minimized the compiler options to:

$ gcc -c -DVERSION=\"6.06\" -DXS_VERSION=\"6.06\" -I/usr/lib64/perl5/CORE -O2 NYTProf.c

It happens since -O2 optimization level. A preprorocessed source with these options is attached.
Comment 1 Jakub Jelinek 2020-03-12 10:36:52 UTC 
Should be fixed in gcc-10.0.1-0.9.fc{32,33}, the f32 version hasn't finished building yet.
Comment 2 Petr Pisar 2020-03-12 12:07:47 UTC 
I confirm that the package builds fine again with gcc-10.0.1-0.9.fc33.x86_64.
