There are a few places where this could break. - The generated dispatch stub function is wrong. - The dispatch offset used by the driver is wrong. - The dispatch remapping used by the driver is wrong. The easiest way to check this is probably to set a breakpoint in _mesa_init_exec_table at the line after the SET_TestExtensionMESA. Look at driDispatchRemapTable[TestExtensionMESA_remap_index]. Does it seem sensible? Look at the function stored in the dispatch table at that offset.
