--- Comment #11 from Gary Mills <gary_mills at fastmail dot fm> --- Well, I got the same ICE when the compiler was built with -O0. It always seems to happen during the configure tests, always this one: configure:3662: checking for suffix of object files configure:3684: /export/home/mills/Downloads/code/oi-userland/components/developer/gcc-7/build/sparcv7/./gcc/xgcc -B/export/home/mills/Downloads/code/oi-userland/components/developer/gcc-7/build/sparcv7/./gcc/ -B/usr/gcc/7/sparc-sun-solaris2.11/bin/ -B/usr/gcc/7/sparc-sun-solaris2.11/lib/ -isystem /usr/gcc/7/sparc-sun-solaris2.11/include -isystem /usr/gcc/7/sparc-sun-solaris2.11/sys-include -c -O2 -g -O0 conftest.c >&5 conftest.c: In function 'main': conftest.c:11:1: internal compiler error: Segmentation Fault Here's some information on the intermediate compiler: $ build/sparcv7/./gcc/xgcc -v Using built-in specs.
