So I'm trying to start janusvr -render vive with the steamvr-osvr steamvr
plugin. Because osvr-rendermanager still doesn't do core profile, I start it
with
MESA_GL_VERSION_OVERRIDE=3.3COMPAT MESA_GLSL_VERSION_OVERRIDE=330 ./janusvr
-render vive
But llvm segfaults:
Thread 12 "si_shader:1" received signal SIGSEGV, Segmentation fault.
