Indeed.

OK, I have recompiled to Lucid, reproduced the problem and indeed your 
patch seems to fix it. With seemingly no adverse effects.

I did get a segfault once when testing this, but wasn't able to 
replicate it so far. Could be unrelated. Attaching both it and the 
"decoded" version, which was produced with this command (note that the 
regexp is different from what the manual advises):

sed -n 's/[a-z0-9_/-]\+(\([a-z0-9+]\+\))/\1/p' segfault.txt | addr2line 
-C -f -i -p -e src/emacs

Not sure if you need the contents of *foo* from me, but attaching it 
anyway (from a different session), because it might show something 
different with 2x scaled display.
