Run your program under a debugger (gdb, for example) and step through the code which you expect to clear the characters.
It's a bit tricky to debug a program which forks, because the debugger will only follow the parent, not the child process. One way around this is to print the PID for the child and have it sleep for a while, which will allow you enough time to attach to the child process.
