[rrd-developers] Seg fault with r1094

I'm not sure if I'm doing something wrong or what.  I know when I submitted
my patch for --full-size-mode my rrdtool calls were working fine.  Since
then, I've discovered an unintended feature where --full-size-mode doesn't
act right with --no-legend.  In the course of trying to fix this, I updated
my working copy to the repo's version of the patch, which apparently
included some other changes then.  Since recompiling from then on it seems
that none of my rrdtool cards are working right.  They segfault on any time
I actually call an rrd (I've only tried info and graph, but probably any
subcommand).  I recompiled with -g -O0 and ran it through gdb, and I got


Starting program: /frogstar/usr/ppc/bin/rrdtool info


Program received signal SIGSEGV, Segmentation fault.

0x0ff6d1cc in rrd_close (rrd_file=0x0) at rrd_open.c:418

418                  ret = munmap(rrd_file->file_start, rrd_file->file_len);


Now I'm sure I didn't change anything in rrd_open, so is this a new bug, or
am I missing something?  I just need to make sure I'm not crazy.
