That's easy to check.  You can dump the assembler output generated by gcc with
"-S" option.
I'm pretty sure the faulting gprel instruction is from gcc.

You can compare .o files generated by new and working compiles with cmp.  You
can disassemble
.o and executables with "objdump -d".

You can link .o file generated with new compiler with old compiler.  You can
also test using HP and
GNU tools.  Use "gcc -save-temps -v" to capture intermediate files and
commands.

I think the issue is more likely with ld than as.
