[Openexr-devel] thread safety on OS X?

[Paul Miller]

I ran into a difference in the way Windows and OS X 10.3 behave when 
using OpenEXR functions from a thread.

First, is it permissable to open an EXR file in one thread and read it 
in another? This seems to "work" on Windows, but crashes horribly on 
Mac. I found out that if I moved the read code completely out of the 
thread, it started working on Mac.

If anyone is interested, I'm using Qt's QThread class.

Is what I am doing technically allowed?
