There is always https://gcc.gnu.org/wiki/CompileFarm There are e.g. 192, 160, 128, 80, 64 thread power machines. Whether any of them can actually reproduce it, I haven't tried. But shouldn't be that time consuming to reproduce, for this kind of thing one can just build .../configure --enable-languages=c,c++,fortran --disable-bootstrap --disable-libsanitizer make -jN compiler and just cd power*/libgomp make check RUNTESTFLAGS=fortran.exp=rwlock*.f90 repeatedly to see if it gets stuck.
