I have submitted: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81315
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
