I'm trying to move a Qt OpenGL project from Qt 4.5 to Qt 4.6. This
project builds & runs on both Qt 4.5 & 4.6 under Windows XP SP3 without
problems on a single core.
However on a dual core (Dell E-Series laptop) with Window XP SP3 it
works using MinGW 3.4.2 & MinGW-TDM2 4.4.1, but when I build it using
VS2005 (& VS2010 Beta2) it suspends repeatedly on startup due to Heap
corruption errors.
The same project appears to build fine on all 4.5.x releases. As far as
I can be certain there are no double deletes performed in my code. I've
tried downloading the Qt4.6 rc1 binaries installer & that does the same
thing. I've tried building it from source locally using vs2005 & that
does the same thing
I've also discovered that with the 4.6.0 rc1 vs2008 pre-built package on
the dual core PC, many of the OpenGL examples crash as does the
qtdemo.exe. Are there any known issues with OpenGL under msvc on multi
core or is this just a very broken system? If so are there any
suggestions anyone can give me as to what could be causing this.
