InternalErrorException: Buffer data corrupted after Ogre update

[fractile]

Ogre Version: stable head
Operating System: Xubuntu 18.10 x86_64
Render System:: GL
GPU: Intel(R) HD Graphics (Coffeelake 3x8 GT2)

I upgraded from Ogre 1.10.x to latest head in "stable" branch and I'm getting this:

Code: Select all

terminate called after throwing an instance of 'Ogre::InternalErrorException'
  what():  InternalErrorException: Buffer data corrupted, please reload in GLHardwareVertexBuffer::unlock at /home/mikko/fractilegames/external/source/ogre/RenderSystems/GL/src/OgreGLHardwareVertexBuffer.cpp (line 164)
Aborted (core dumped)

Core dump shows this:

I'm guessing this has something to do with instancing, but 1.11 change log does not mention any relevant changes there. There appears to be two problems: failing Ogre::GLHardwareVertexBuffer::unlockImpl() and crash on exception handling.

Any ideas on what's going on here?

Edit: The 1.11.5 release version works fine.

can you reproduce this with the Sample Browser? Might be this commit https://github.com/OGRECave/ogre/commit ... 916f30ca5a

I tried reverting the single commit, but it did not change anything. This is not reproducible with sample browser, "New instancing" sample (and all others that I tried) works fine.

I'll stick to 1.11.5 release for now.
