>Description:
Compiling the attached tkh.i, a condensed version of bfd/tekhex.c from binutils with

gcc -O2 -fPIC -c tkh.i

fails with an ICE:

tkh.i: In function `tekhex_init':
tkh.i:35: virtual array reg_n_info[169]: element 169 out of bounds in load_mems, at loop.c:9827

Either using -O or without -fPIC succeeds.
>How-To-Repeat:
Compile attatached tkh.i as detailed above.
