RE: [Openexr-devel] stack overflow in openexr

[Luc-Eric Rousseau]

We actually had this stack overflow problem on Linux, as the OpenEXR code was 
running a secondary thumbnail thread which didn't have enough stack.  We 
changed it to use the Windows code.  I don't think it's a great candidate for a 
platform define, it just assumes a lot of stack is available no matter the 
plateform.  Ideally it should be changed to allocate from the heap after a 
certain threshold.
