gpu crash dump
this seems to happen occasionally when emacs runs into a "deviant" (of some
sort) character (i use various non-US alphabets). in this case, it was a
"_a_", (0x5f, 0x61, 0x5f) which emacs would like to render as underlined.
this could be an duplicate of 93166.
here are the syslog messages (of two back-to-back occurrences):
