Thanks SO much! I'm hoping the new rsync 2.5.6 binary I provided to the client resolves the problem - but if not, I'm certainly armed with EXCELLENT information on how to proceed.
Thanks for taking the time to write this up! You rule...
Have a great day,

I forgot to say:
You must specify *both* the executable file name and the pid. Otherwise, you
don't see function names, only raw addresses.
gdb rsync.exe <pid>
Also, try gdb first. On all but WinXP (and possibly 2k, I don't know),
detaching from a process kills it. So you only get a chance to try one of

Make that "thread 1", then "bt".
