--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
I can reproduce the SEGV with the same stack trace with recent trunk.

Going back in time as far back as commit 8b2ddcd 7 months ago I get:

lto1: internal compiler error: Segmentation fault
0x10697533 crash_signal
        /build/gcc-65243/trunk/gcc/toplev.c:337

...and with commit 757abb4 the month before I get:

lto1: fatal error: LTO_tags out of range: Range is 0 to 384, value is

compilation terminated.
