--- Comment #33 from Joshua Kinard <kumba at gentoo dot org> --- The problem may be tied to a particular CFLAG on glibc-n32 MIPS. I ran our (Gentoo's) stage-building script, and forgot to block gcc-5.3.0 from building, and it ended up completing. Difference between that script (which builds inside a chroot) is I used saner CFLAGS. The CFLAGS I am using in my rootfs that fails to build gcc-5.3.0 is: CFLAGS="-O2 -pipe -march=r12k -mtune=r12k -mno-fix-r10000 -mabi=n32 -mplt -fomit-frame-pointer -fforce-addr -fivopts -fmodulo-sched -ftree-vectorize" LDFLAGS="-Wl,-O2 -Wl,-z,now -Wl,-z,relro" So I'll look at dropping one flag at a time, along with trimming LDFLAGS, and see if I can pin down which one causes ./genmatch --gimple to segfault on N32.
