We have the following failures on SPARC:
FAIL: gfortran.fortran-torture/execute/userop.f90 compilation, -O0
FAIL: gfortran.fortran-torture/execute/userop.f90 compilation, -O1
FAIL: gfortran.fortran-torture/execute/userop.f90 compilation, -O2
FAIL: gfortran.fortran-torture/execute/userop.f90 compilation, -O3

FAIL: gfortran.fortran-torture/execute/userop.f90 compilation, -O3
-fomit-frame-pointer -funroll-all-loops -finline-functions
FAIL: gfortran.fortran-torture/execute/userop.f90 compilation, -O3 -g
FAIL: gfortran.fortran-torture/execute/userop.f90 compilation, -Os
The problem is at resolve.c:1418:
sprintf (msg, "Operands of user operator '%s' at %%L are %s/%s",
e->uop->ns->proc_name->name, gfc_typename (&op1->ts),
gfc_typename (&op2->ts));
e->uop->ns->proc_name is NULL. So an out-of-bounds address is passed to sprintf
and we get a SIGSEGV inside the libc. Note that we don't get it with a
cross-compiler on Linux/x86, but the address is NULL there anyway.

Putative patch
Try this please. The original code looks like it is a relic from some past time
where operators kept their names in their own namespaces. I don't know if that
time ever existed.

Sorry, I forgot to actually submit this patch :( Applied as obvious after
re-testing. Fixed.
