Crash to desktop Win10 large registration

[mutti-wilson]

@oleg68 asked for a crashdump to see what's going on. Crashes after playing large registration.

I'm using the latest 3.4.2-0.2 build by @oleg68

GrandOrgue.exe.8792.zip

[oleg68]

@mutti-wilson Please try to use grandorgue-3.4.2-1.847.1.windows.x86_64.zip
(without installation; just unpack it to some directory and run bin\GrandOrgue.exe) and post here the new crash dump from this version.

[mutti-wilson]

Here are 2 crash dumps. I don't know why they have a duplicate file name since the time generated is the same but they are slightly different sized so I thought sending both would be wise.

So if it matters I have a little info to add as well as another crash dump. The first crash was using WDM drivers, second was ASIO and this crash was using Direct Sound. Direct sound lasted the longest before crashing. If you need any other background let me know and I'll do what I can to answer. Thanks for digging in on this.

Thank you, @mutti-wilson I will discover your crash dumps.

• The same as asio.

So this problem seems relates neither the sound driver nor windows, but when the same pipe is referenced from different ranks.

Another possible reason - the metronome.

[oleg68]

@mutti-wilson Could you try the new version?

When it crashes then post the crash dump here.

What organ are you playing? Is the metronome switched on when GO crashes?

[mutti-wilson]

@oleg68 I am using Friesach. I've never used the metronome. I remember poking around in the ODF for some reason but I don't think I made any changes. I will check and see if the metronome got switched on somehow. I'll dig around and try out the new version tonight as well. Does the debug log point to any pipe specifically?

[mutti-wilson]

@oleg68 I used the new build and played for almost 2 hours with all stops and couplers pulled and experienced no crashes. I changed back to ASIO because I feel like the latency is superior and knowing that it crashed often using ASIO I thought that would be a good test. Seems like it's fixed. I have an untouched ODF of Friesach that I did not try as it would be too many variables and harder to pin down what actually fixed it.

[oleg68]

@mutti-wilson Thank you for your test. It is not a final fix yet, but I'll work on it for the official version.

[oleg68]

@mutti-wilson please try the official intermediate build with fixing this issue

[mutti-wilson]

@oleg68 I will install this when I get home this evening.

[mutti-wilson]

@oleg68 This build worked great. No crashes at all. Thanks so much. I'm back in business and hopefully others will benefit from this fix as well.
