Status: UNCONFIRMED
Keywords: openacc, wrong-code
Severity: normal

OpenACC 2.7 (same in 2.6), in section 2.6.1. "Variables with Predetermined Data
Attributes" mandates that "Variables declared in 'seq' routine are private to
the thread that made the call. Variables declared in 'vector' routine are
private to the worker that made the call and shared across the threads
associated with the vector lanes of that worker. Variables declared in 'worker'
or 'gang' routine are private to the gang that made the call and shared across
the threads associated with the workers and vector lanes of that gang".
