The Sascha pushconstants demo fails on Mesa 11.3.0-devel (git-62c728f) App source: https://github.com/SaschaWillems/Vulkan/tree/master/pushconstants Failure message: src/compiler/spirv/vtn_variables.c:1047: var_decoration_cb: Assertion `!"Unhandled variable decoration"' failed. Debug information: (gdb) p *dec $1 = {next = 0x0, scope = -1, literals = 0x8cbd38, group = 0x0, {decoration = SpvDecorationArrayStride, exec_mode = SpvExecutionModePixelCenterInteger}}
