I can reproduce it quite reliably. I'm not sure I'm at the correct
revision, but I just tried this again at revno 108581 with the same
results.
I tried 108257 (which seems to be from May 17? Not "today"?), and also
got the same result. It seems to take a little while for the segfault
to occur. Trying a few motion keys (C-n, C-e, C-a) seems to trigger it
for me.

Sure thing:
Program received signal SIGSEGV, Segmentation fault.
0x0000000000438649 in handle_face_prop (it=0x7fffffffb180) at xdisp.c:3689
3689 = (it->current.overlay_string_index >= 0
(gdb) p it->current
$1 = {
pos = {
charpos = 1,
bytepos = 1
},
overlay_string_index = 1935,
string_pos = {
charpos = 0,
bytepos = 0
},
dpvec_index = -1
}
Thank you for your interest,
