Confirmed.
I tracked it down to the CapCheck function at https://github.com/KhronosGroup/SPIRV-Tools/blob/master/source/validate_instruction.cpp#L87
For operands that are IDs, it should not be checking the ID value itself, but rather the underlying constant if it can find one. Note that we should have a one-sided error, i.e. if we can't determine the value then let it pass. (This might occur if there's a complex expression the code doesn't know how to evaluate.
Looking at the operand types in libspirv.h, this kind of problem would only affect SPV_OPERAND_TYPE_MEMORY_SEMANTICS_ID (as in this reported but), or SPV_OEPRAND_TYPE_SCOPE_ID, but none of those values have required capabilities.

Workaround has been merged. I filed #252 for the "proper" (completist) fix.
