[ITK-users] [ITK] bug in imageIOFactory

[Matt McCormick]

Hi Scott,

According to this [1] entry in the HDF5 FAQ, to get a thread-safe
version on Windows, a new version is required with the referenced
CMake option enabled.  If this is done with ITK_USE_SYSTEM_HDF5
enabled, does it fix the crash?

Thanks,
Matt
