Hello folks,
    I am using Rhide IDE and having problem  allocating memory. The graphic
display program involve the following segment which I suspect could be the
problem.
The program run ok just once, then after exit with return 0 from main(good
status), it couldn't be executed a second time from Rhide. The Rhide get
hanged, mouse cannot activate any menu command at all. Have to quit Rhide
and run the program again. Sometimes the error bin/ld.exe cannot find
svga02.exe appear and need to restart the computer again.  Even the
free(offscreen) at the end does not make a difference.
Hope some of you can help in solving this. Is this a legal operation for
640*480 size?

byte *offscreen;
offscreen= (byte*)malloc((640*480)*sizeof(byte));
..
..
free(offscreen)

Thank you
Patrick
