With 23be03a0f243a084a0fe03d0b96a3d045e1a2b65 (r11-7965)
the g++.dg/modules/xtreme-header-2_b.C test started to fail with an ICE for
cris-elf, thus:
Running /X/gcc/testsuite/g++.dg/modules/modules.exp ...
...
FAIL: g++.dg/modules/xtreme-header-2_b.C -std=c++2b (internal compiler error)
FAIL: g++.dg/modules/xtreme-header-2_b.C -std=c++2b (test for excess errors)

I don't see this for other targets on gcc-testresults@. Also, it looks like
-save-temps doesn't help here, so please instruct on how to help me help you
with the equivalent information.
