printf(arg) instead of printf('s', arg).I have seen it done way too often.

The problem is that if I try to put this exact same code into a separate function called crystalkeystroke(), change the last line to return response.data0 as the result, and call 'int keypress crystalkeystroke()' from main, the program craps out with a backtrace and the complaint 'Stack smashing detected. It is possible to have issues with printf(), by using as format string a user-provided argument, i.e. I would have pasted the code here but its approx 2000 lines. Audio comes out the head phone jack, but all of this stuff get written to the command line. I am stuck for 1 week in a stack smashing detected bug in my C program running in a i386 desktop with Ubuntu 7.0.4.
