glGetError() retains error once error occurred. Calling glGetError()
returns last error code and clears the error state. Hence you should add
a dummy glGetError() call before glCreateMemoryObjectsEXT() to clear the
potential stale GL errors, otherwise your code will handle unrelated GL
errors and report them as memfd import failures.
