I think a segfault from gcc generally points to bad memory (RAM). Can you run memtest for a few hours to see if you get any errors?
(In reply to comment #1) I'll run it overnight.
Reran the emerge command and it completed successfully, so this may well be a memory problem.
Okay. Reopen if you get a consistent failure.
Left memtest86+ running Friday night; workstation rebooted on Saturday. Started memtest86+ last night; still running when I came in this morning, no errors.
Ok. Can you reproduce the compiler error?
No; I re-emerged chromium overnight without error.
(In reply to comment #7) > No; I re-emerged chromium overnight without error. By the way, I think it was ccache.
How can ccache cause an internal compiler error? Presumably everything in ccache has already been through the compiler without error. Thanks.
