Hi,

i get the same warning/error on s390.
Compiling lasts about 10 seconds without the pragmas.

Bye Stefan

I did not dig into this issue from compiler side, bug checking on bugzilla
it might due BZ#59884 [1].  Nevertheless this is an existing issue.

I suppose these pragmas could be made conditional on i386 or x86_64 --
the problem they are trying to work around is present in the x86 GCC
backend, but not necessarily in other backends.

Adhemerval,

If you simply delete the #pragma's from generated test source, does
the resulting source compile with -O2 in reasonable time?

Thanks,
