shared_memory_object does not initialise m_mode in default ctor

Reported by: Graham Hudspith <graham.hudspith@…> Owned by: Ion Gaztañaga
Milestone: To Be Determined Component: interprocess
Version: Boost 1.51.0 Severity: Problem

Description

The default ctor for shared_memory_object does not initialise the m_mode member.

I can't find an enum/#define for the "zero" value of mode_t, so I guess a simple: 

inline shared_memory_object::shared_memory_object()
   :  m_handle(file_handle_t(ipcdetail::invalid_file())),
      m_mode(0) // <--- this is the new line
{}

would do the job.

Reported to us when we run a static analysis program on our code which uses the boost interprocess library.

This is against the 1.51.0 release of boost, but I've checked your svn trunk and it is still there.
