rsync 2.6.2 crashing (was: No Subject)

I'm using rsync/ssh/cygwin to sync two very large directory hierarchies. While testing with one of the subdirectories (this subhierarchy has about 1000 subfolders and 17000 files), I experience the following behavior:

rsync 2.6.2 on both ends.

Client command: 
rsync -v -v -r --delete -t --progress --rsh="ssh -l mpdm -i ADMIN/rsa-mpdm01" MPDM-W2K3::"MPDM/17B - CONTROL" "17B - CONTROL"

Server entry in ~mpdm/.ssh/authorized_keys: 
command="rsync --server --daemon ." ssh-rsa <key>

    path = /cygdrive/g
    read only = true

Client ouput: 
opening connection using ssh -l mpdm -i ADMIN/rsa-mpdm01 MPDM-W2K3 rsync --server --daemon .
receiving file list ...
[receiver] expand file_list to 131072 bytes, did move
 2000 files...
rsync: read error: Connection reset by peer
rsync error: error in rsync protocol data stream (code 12) at /home/lapo/package/tmp/rsync-2.6.2/io.c(354)

The server crashed, but left rsync.exe.stackdump:

If I change the command entry in authorized_keys to:
command="/usr/bin/strace -o/tmp/rsync-strace.out -f /usr/bin/rsync --server --daemon ." 

The server doesn't crash; instead, it just hangs somewhere in the middle of copying the data, which is further along then without strace. I can provide the strace output if that would help.

Any suggestions?
