(gdb) run
Starting program: /usr/src/rsync-3.0.0/rsync --daemon --server .
Reading symbols from shared object read from target memory...done.

when i comment out this line (loadparm.c:838), there is no segmentation fault any more.

See the mailing list:


This is already fixed in the git repository and the nightly tar files.
