Rather than return an error code as documented, Framecopy_execute() uses an assertion to test its parameters and aborts if it is passed a NULL pointer.
This means that the caller is not informed of the error and does not have the opportunity to report the error. So, instead of an error message from an application module, the developer sees something like:
Framecopy.c:262: Framecopy_execute: Assertion `hFc' failed.
Aborted
with no clue as to where it occurred.
How do I report this as a bug?
