sh4 is:
during RTL pass: final
In file included from strtof_l.c:45:
strtod_l.c: In function '____strtof_l_internal':
strtod_l.c:1769:1: internal compiler error: Segmentation fault

Since it's in maybe_output_next_view, I think it probably comes from these
patches.

hppa has a similar ICE building glibc tests, also in
maybe_output_next_view, so probably also from these patches:
during RTL pass: final
test-tgmath2.c: In function 'test_fma_3':
test-tgmath2.c:421:1: internal compiler error: Segmentation fault
}
