rsync is coring

We are running the following version of rsync:

-rwxr-xr-x    1 root     system       235216 Sep 27 2004  rsync

I ran dbx which gave me this:

[using memory image in core]
reading symbolic information ...warning: no source compiled with -g

Segmentation fault in . at 0x100236e0
0x100236e0 (???) 8c040001        lbzu   r0,0x1(r4)

It looks like since the program was not compiled with the -g option it is 
not providing adequate debug info.

Would appreciate any thoughts.

Two things you can do:

- Open the core file in a debugger and get a stack trace.

- Try to reproduce the problem on a smaller set of files or with simpler
options, etc., until you find a minimal case that fails.  This may shed
light on what is causing the problem.  If the same minimal case fails on
another machine, that is probably grounds to file a bug.
