Research direction

Start by inspecting thirdparty/spirv-reflect/spirv_reflect.c at lines 293 and 2205, then determine how to reproduce the reported sanitizer diagnostics since the issue provides no reproduction steps. Run the relevant sanitizer configuration against a reproducing input; done means both reported diagnostics are resolved and the sanitizer run is clean.
