[Gluster-devel] glusterd crashes when synctask is used in conjunction with inner functions.

[Krishnan Parthasarathi]

Oops. I misunderstood the argument to be argument to the inner
function as opposed to command line argument to the program.
Experiment worked!

thanks,
krish

Are you sure you ran it both with and without arguments?  Without arguments it
doesn't overwrite the stack and you won't see a crash with either version.
With arguments it does overwrite the stack and you should see a crash (I did)
with either version.
