Window / Crash in WindowImpl() when overloading global new/delete g++

« on: July 24, 2010, 11:40:29 pm »

I've recently been trying to migrate from Visual Studio over to MinGW w/g++.  Now that I've got everything compiling and linking again, I'm getting a crash in the constructor for WindowImpl().  It appears to have something to do with the stl:deque class (I'm assuming it's something to do with the myEvents member variable).  It looks like it's either attempting to delete a bad pointer or, it's trying to delete something that it allocated with a version of new other than my overloaded new.  I've been trying to debug this with gdb, but I'm a gdb noob.

Here's the call stack:

#1  0x00465767 in operator delete (Memory=0x344b28) at Native/DF_Common/DF_Memory.h:46

#5  0x0044c1d6 in std::_Deque_base<sf::Event, std::allocator<sf::Event> >::~_Deque_base() ()
#6  0x004582ce in std::deque<sf::Event, std::allocator<sf::Event> >::~deque() ()
#7  0x00402fcf in sf::priv::WindowImpl::WindowImpl() ()
#8  0x00403a9b in sf::priv::WindowImplWin32::WindowImplWin32(sf::VideoMode, std::string const&, unsigned long) ()
#9  0x00402f13 in sf::priv::WindowImpl::New(sf::VideoMode, std::string const&, unsigned long) ()
#10 0x004022e7 in sf::Window::Create(sf::VideoMode, std::string const&, unsigned long, sf::ContextSettings const&) ()
#11 0x004020f6 in sf::Window::Window(sf::VideoMode, std::string const&, unsigned long, sf::ContextSettings const&) ()
#12 0x00401457 in Init (hInstance=0x400000) at Native\DF_Game\Main.cpp:160

This does not happen with Visual Studio and its version of STL.  Nor does it happen with MinGW/g++ if I don't overload global new/delete.

Any ideas and/or suggestions?[/code]
