64 Bit IL VST Plugins crash in Bitwig Studio 1.1 Beta 5

[Thomas Helzle]

Hey,

we have user reports that as of Bitwig Studio 1.1 Beta 5, all 64 Bit Image Line VST plugins crash.
Something changed in the application, one of the devs says:

---------------------------------
"Only the 64-bit versions crashing? This definitely sounds like a bug in their 64-bit ports.

Since 1.0.x we've changed a linker setting on windows which makes it much more likely (like 100% likely) that any memory pointers we pass to the 64-bit plug-in actually isn't just zeros in the upper 32-bits but is a nice big juicy 64-bity number. This is a good thing to do as it makes it harder to hack etc etc but much more importantly it allows us, users and other developers to catch 32-bit to 64-bit porting errors early where the developers forgot to update the code properly. So instead of passing the plug-in pointers with all upper zeros letting the plug-in load thinking everything is fine (and crash at you randomly later) it will crash instantly.

Now, that might sound odd that that's supposed to be better but every developer worth anything knows that pretending bugs aren't there aren't gonna fix them. And this is the kind of bug that can crash on you randomly or when you add the plug-in to a project which is already quite full. Maybe you need 17 Kontakts loaded in RAM before adding the plugin for it to happen but that makes it even more annoying when it does.

So what should you do about it?
1) Tell the developer to stop truncating the upper 32-bits of 64-bit pointers
2) Use the 32-bit versions until they issue a fix
-----------------------------------

Can this be fixed? If you don't have the beta in your Bitwig user-account already, they can provide you with a NFR I'm sure.

Thanks a lot!

Cheers,

Tom
