--- Comment #1 from Seth Johnson <johnsonsr at ornl dot gov> ---
- Correction in test case: `call dellocate(` should be replaced by
`deallocate(` (but this doesn't affect the behavior or test outcome
- Also note that the Fortran 2003 standard itself includes a structurally
identical example in "C.10.2.4 Example of opaque communication between C and
Fortran", if further evidence is needed that this is allowable with
`-std=f2003` and `-std=f2008`.
