--- Comment #31 from Gary Mills <gary_mills at fastmail dot fm> --- When I built gcc-7 with even more configuration options, including --enable-initfini-array, I got this segmentation fault on SPARC hardware: 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 -g -O2 -mno-app-regs conftest.c >&5 conftest.c: In function 'main': conftest.c:11:1: internal compiler error: Segmentation Fault main () ^~~~ conftest.c:11:1: internal compiler error: Abort xgcc: internal compiler error: Abort (program cc1) This is a known problem, and an old one. The --enable-initfini-array option is not shown in the help output from gcc-7 configure. When I did a subsequent build without that option, I got a successful build. It's quite possible that this option was the source of all the problems.
