Re: [Dev-C++] segmentation fault at runtime

[Per W. <pw...@ia...>]

Wait a minute.

m_pSrv is a pointer pointing to an object.

KviIrcServer* beConsole::server()

should return a pointer, i.e. the contents of m_pSrv, i.e.
  return m_pSrv;
and not a copy of an object as is done by
  return *m_pSrv;

When a function returns a pointer, this of course doesn't mean that it
returns the address of the pointer, but the value stored in the pointer,
i.e. the address of an object.
