Just ran into this when zooming in to the end of a track that I had
just applied an effect to: Crash: blockStatus uninitialized Sequence::GetWaveDisplay line 1248 bl[pixel - 1] = blockStatus;//mchinen Traces back to WaveClip::GetWaveDisplay 673 TrackArtist::DrawClipWaveform 1263 TrackArtist::DrawWaveform 1084 TrackArtist::DrawTrack 256 etc. May be related to crashes with applying effects when zoomed in? No time to look into it right now. TTFN Martyn ------------------------------------------------------------------------------ Come build with us!

Actually, that's annoyingly repeatable here (XP VS 2008):
Generate chirp, 30s, 0->0.8 amplitude Effect -> Change Speed... -> 10 -> OK Mouse over the RH end then mouse-wheel forward Just as it looks like it might get to display samples... boink!

Ha! This is related to the problem of creation of extra clips.

I have been looking at this problem of extra clips for some time now. Will start a separate thread soon. Vidyashankar

So is there a fix for this or a change that we should revert?

Is it zooming causing this again (CTRL + Wheel rotate according to the Mouse Preferences)? Wheel Rotate is scroll up or down. FWIW I only have a wheel-less mouse. I get the superfluous clip at the end of the track after applying Change Speed, but I don't get any crash clicking near the track end and zooming (in Win XP Unicode Release).

I just built a fresh unicode debug from HEAD. The bug is repeatable for me in winXP. But surprisingly, my stack trace looks different.

TrackArtist::DrawIndividualSamples 953 TrackArtist::DrawClipWaveform 1295 TrackArtist:DrawWaveform 1084 In Unicode Release mode, obviously there is no wxASSERT. So no crash is seen.
I still feel the problem is with the spurious clip at the end. When the spurious clip is present, the crash happens when I zoom in for the 10th time. (Generate Chirp 30 sec, Change speed 10% and start zooming at the end)
I recently started a separate thread on the spurious clips. Without the spurious clip, I can zoom in to the maximum extent without any problems. However, looking at the different stack trace in Martyn's case, it may be a different bug in itself. Martyn, if you have time, can you apply the patch I submitted in the thread on spurious clips and see if the 'blockStatus uninitialised' bug is still there?

This wxAssert problem seems to be present when continuously zooming in on any split line. (For example, generate chirp 30 sec, split at 5 sec, keep zooming in on the split line). So it is not related to the presence of spurious clips. This wxAssert bug is different from the subject of this thread. I am still not able to replicate the uninitialised block bug that Martyn got. As he mentioned, it is probably related to the P2 'crashes with applying repeated effects when zoomed in'. I will look into it more and see if I find anything.
