--- Comment #2 from Sam James <sjames at gcc dot gnu.org> ---
I was confused at first while just checking the range because 10 has a
different ICE:
$ g++-10 /tmp/foo.cxx -o /tmp/foo -c -O2 -m32 -flive-range-shrinkage -fno-dce
-fnon-call-exceptions
during RTL pass: lr_shrinkage
/tmp/foo.cxx: In member function 'void SQVM::CallNative()':
/tmp/foo.cxx:41:1: internal compiler error: Segmentation fault
41 | }
