[ITK] [ITK-users] bug in imageIOFactory

[Bradley Lowekamp]

Hello,

If it's just the HDF5ImageIO module that is causing the threading issue, then have you considered just disabling that ITKModule when building ITK?

You may also be able to explicitly set the ImageIO to the ImageFileReader, so that that IOFactory is not used to determine the ImageIO to use.

Hope that helps,
Brad
