[Bf-committers] MinGW debug builds do not run

IIRC MSVC2008 full version is used for releases,
I have a free MSVC2010 which has a similar problem to MinGW, debug
builds fail to run with strange popup dialog error.
Re Crash on startup:
If its a crash (not a linking/error message), best not assume blender
is without fault, debug info & call-stack can help a lot in tracking
down these problems.
The IOError define is already in lib/windows, committed shortly after
changing the exception.
I use an update alias which does both repo's before building to
prevent these kinds of errors.
Do you still get the crash on startup?
