Crash in WebCore::TextureMapperShaderProgram in secondary thread while _mesa_destroy_shader_compiler is running in exit handler. I have no truncated backtrace for this, just check the full backtrace in the downstream bug, threads 1 and 2. I guess either WebCore::TextureMapperShaderProgram is doing something that is not threadsafe, or maybe it needs to install its own exit handler.
