Otherwise unrelated to this bug though. valgrind: ==30990== Invalid read of size 8 ==30990== at 0x9F90847: ast_interface_block::hir(exec_list*, _mesa_glsl_parse_state*) (ast_to_hir.cpp:5688) ==30990== by 0x9F875FC: _mesa_ast_to_hir(exec_list*, _mesa_glsl_parse_state*) (ast_to_hir.cpp:100) ==30990== by 0x9FDB07A: _mesa_glsl_compile_shader (glsl_parser_extras.cpp:1462) ==30990== by 0x9EB843D: compile_shader (shaderapi.c:849) ==30990== by 0x9EBA1AD: _mesa_create_shader_program (shaderapi.c:1830) ==30990== by 0x9EBA7C7: _mesa_CreateShaderProgramv (shaderapi.c:1919) ==30990== by 0x6C29EED: shared_dispatch_stub_892 (glapi_mapi_tmp.h:20555) ==30990== by 0x404B0D: main (in /recording/download/20140803/mc/mc) and a number of further errors in that function, then later the gallium state tracker throws an assertion: ../../src/mesa/state_tracker/st_glsl_to_tgsi.cpp:2104:visit: Assertion `var->data.location != -1' failed. In release mode this check drops through and the r600 tgsi translator rejects it with: EE ../../../../../../src/gallium/drivers/r600/r600_shader.c:353 tgsi_is_supported - unsupported src 0 (dimension 1) and replaces the shader with a no-op dummy shader to not crash. Basically the gallium driver layer is getting bad data out from the GLSL compiler. -- You are receiving this mail because: You are the assignee for the bug.
