1. load ks1.3_test.adf on WinUAE (config: A5001.3 with 512Kb slow ram expansion)
2. on the prompt, enter "main" then press return

What I expect it to do : play a module for approx. 30 seconds
What happens : usually it hangs after a couple of seconds, then goes to a guru. Sometimes it will play properly for 30 seconds, then if I restart the same exe a second time, it hangs after a couple of seconds.

Note : 
 * works OK on a "A1200" WinUAE config.
 * the same code compiled for the "original" ptreplay lib works OK on a 1.3 config (but it lacks the super good features of your version :))
