Bug ID: 81669 Summary: trunk/gcc/fibonacci_heap.h:58: possible missing initialisation ? Product: gcc Version: 7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: dcb314 at hotmail dot com Target Milestone: --- trunk/gcc/fibonacci_heap.h:58]: (warning) Member variable 'fibonacci_node::m_data' is not initialized in the constructor. Source code is fibonacci_node (): m_parent (NULL), m_child (NULL), m_left (this), m_right (this), m_degree (0), m_mark (0) { } Probably harmless, but might be safer to make sure m_data is set to something sensible.
