--- Comment #4 from sandra at gcc dot gnu.org --- OK, there are two flavors of failures being diagnosed by the test case. The first flavor involves the lower bounds of an array passed into a bind(c) procedure being set to zero in the callee when the test case thinks they should be inherited from the array in the caller. I'm still trying to grok what the standard actually says about these cases. The second flavor looks like the same bug as PR93308, involving the lower bounds of an array passed to a bind(c) procedure appearing to be correct in the callee, but set to zero in the caller after return.
