I have submitted: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D81315 for the below, presuming for now that the problem is on the GCC side of things. Hopefully it is not tied to include-fixed/ now being empty. [We will see if the GCC folks object to the include-fixed/ having empty or not.] I was trying to build lang/gcc7-devel on FreeBSD head -r320570 on a powerpc64. The xgcc stage got the following segmentation fault. (By contrast 32-bit powerpc's build completed without having this problem.) And the crash was repeatable: the below is from a -save-temps rerun. xgcc: warning: -pipe ignored because -save-temps specified Reading specs from =
