Is there any chance you can test this on i586 as well?
Since around that commit (August 27th) my i586 builds are failing
with something like
during GIMPLE pass: pre
cp-demangle.c: In function ‘d_print_comp’:
cp-demangle.c:5711:1: internal compiler error: Segmentation fault
5711 | d_print_comp (struct d_print_info *dpi, int options,
| ^~~~~~~~~~~~
when doing a regular bootstrap on i586-unknown-freebsd10.4 (with
clang 3.4.1 as system compiler).
Alas, when I add -save-temps, the internal compiler error goes away,
and the backtrace using gdb installed on that system I share isn't
very useful, either. (When I replace cp-demangle.c by cp-demangle.i
in the invocation the error also disppears.)
On the other hand, this ICE has been consistent across a week of
daily builds now.
