Do you have any idea why this might occur. I can confirm that this is the only line of code that changes in the entire program and when I went through it with a debugger, the print line does execute.
When using printf() the output is buffered (pending) until you 'flush' it out with a newline character, call fflush(stdout); or when the whole program terminates (and exit() flushes all non-empty output streams). If you want to always immediately flush all output (i.e. it is no longer buffered), add setbuf( stdout, NULL ); very early in main()
