Fully patched 64-bit Ubuntu 18.04LTS Intel I7 AMD Radeon HD 7950 open-source drivers. Is this fixed in 18.10 or 19.04? And did you try the test program? And looking at https://packages.ubuntu.com/bionic/libs/libosmesa6, I don't see the dependency on llvm.

To show this I'm attaching a modified version of mesa-demos-8.4.0/src/osdemos/osdemo.c (from ftp://ftp.freedesktop.org/pub/mesa/demos/mesa-demos-8.4.0.tar.gz). The modified code is all within the #ifdef USE_CORE_CONTEXT. To compile it, do "gcc osdemo.c -lGLU -lOSMesa -lm". With the libOSMesa.so.8 from Ubuntu 18.04, it fails with "OSMesaCreateContext failed!".
