1. Open attached score (produced in 1.3).
2. 'Play'.
3. When playback finishes, enable 'Loop'.
4. 'Play'.

Result: Crash.

Note: See attached log. It crashed when the playback head was on the end barline.

Discussion: I don't know if Loop is the cause and I was only able to reproduce once - the steps are estimated.

On Vista, crashes in the third repetition.
Score created with 1.3, with lyrics (also saved as xml, same behavior)
Score created with R.706355c, without lyrics, as above.

Yes. Steps may vary.

Logs 4 (after first repeat played) and 6 (after maybe half a dozen) used the mscz.

For Log 5, it crashed after the first play using the MusicXML (seemed also to be the case for Log 6).

This is fixed by not calling a fonction (loopstart()) from the sequencer thread. The crash is solved but the looping is far from perfect. The time between two loops is not 0.
