cdc debug console hangs with repeated data

We've a project that uses the K64 usb port as a CDC serial port using the debug console with SDK 1.3 with PE , but it hangs when data is sent regularly to it.


I've stripped the program back so it's just calling debug_getchar();

and then sending that char straight back out with  debug_putchar(temp);


I used termite (a simple terminal program) just to send back a test message, so the whole thing will keep looping, after a few minutes the K64 will crash.


Any thoughts?
