Bug description:
[Impact]
A new fix has been merged to NVIDIA libglvnd repo at
https://github.com/NVIDIA/libglvnd/pull/171/commits/9948df636708e2915e5c2daa61b318e6252bc02e
We need to include it in bionic.
It would be ok to just include this fix even without updating to the latest
glvnd version.
This change fixes a crash seen in some GLX apps while calling
glXGetProcAddress.
Source Package :
https://launchpad.net/ubuntu/+source/libglvnd/1.0.0-2ubuntu2.2
Can we get this fix merged in current LTS 18.04 as "-updates"
[Test app]
To reproduce this failure: Install python-pyglet on 18.04 ubuntu.
And run a small test app with this piece of code.
void *handle = dlopen("libGLX.so.0", 2);
glXGetProcAddressARB = (GLXextFuncPtr (*)(const GLubyte*))dlsym(handle,
"glXGetProcAddressARB");
glXGetProcAddressARB("glXAllocateMemoryMESA");
[Regression potential]
Minimal, disco shipped with the fix.
