agree Smilie. However in repeated runs, the program variables are allocated the same memory location.
Even on reading in a very large string (20 chars) and sending it to sprintf, it is surprising how there is no segmentation fault.

At some point, unless 'k' is pointing to stdout, the length of the memory should cause violation, and program should get SEGV right?

Also, if at all 'k' points to stdout, on doing a flush immediately, i should see the contents of 'k' right? coz it sould overwrite previous contents of stdout.

GL-117(6)							  gl-117 overview							 GL-117(6)

NAME
gl-117 - an OpenGL action flight simulator SYNOPSIS
gl-117 [-dlevel -h -v] DESCRIPTION
gl-117 is an OpenGL and SDL based action flight simulator written in ISO C++. Enter the Eagle Squadron and succeed in several challanging missions leading though different landscapes. Five predefined levels of video quality and an amount of viewing ranges let you perfectly adjust the game to the performance of your system. The game provides joystick and mouse support, sound effects, and music. OPTIONS
-dlevel Set the debug level to level in [0..5]. '0' means quiet and will avoid any output, '1' will log fatal errors causing the program to crash on stderr, '2' will also print exceptions on stderr, '3' will add warnings on stdout, '4' prints additional information (pre- defined) on stdout, and '5' gives developer specific messages on stdout. -h Print a short summary on stdout and then quit immediately. -v Display the version number of gl-117 and then quit immediately. CONFIGURATION
gl-117 uses a predefined working directory ".gl-117" in the user's home directory to load and store all savegame files and read the plain text configuration files "conf" and "conf.interface". If there are no config files available, gl-117 will create them using standard set- tings. The contents of the files are quite self-explanatory. DOCUMENTATION
Please look at the gl-117 user manual (gl-117.pdf) for installation instructions and further gameplay related descriptions. COPYRIGHT
gl-117 is distributed under the terms of the GPL. AUTHORS
