It took me a long time to get back to this issue because I was busy
with a couple of other things but the attached patch which was
generated against CVS HEAD fixes the problem for me (i.e., avoids the
segfault in gdb and gets me readable backtraces). Is there something
else I could do to help get this issue fixed in mainline ?
