That one appears on all sparc-solaris2.* testresults, for
gfortran.dg/cray_pointers_2.f90. Minimal set of flags to reproduce:
-funroll-loops -fcray-pointer -O1 (it works OK at -O0 or without loops
unrolling).
$ gfortran cray_pointers_2.f90 -funroll-loops -fcray-pointer -O1 && ./a.out
zsh: segmentation fault ./a.out
Don't know if I'm supposed to mark it target or tree-optimization, please
correct if I did it wrong.
