Ed,

Thanks for your help. Could you please confirm that there is a link in between testOptimizedInterleavePatterns.cpp and testBoxAlgo.cpp ? issue #67 only relates to testBoxAlgo.cpp and testBox.cpp issues. While my original post mentionned issue with testOptimizedInterleavePatterns.cpp.

Thanks for further comments.

It is noted in the comments for this issue: https://github.com/openexr/openexr/issues/67  Per the latest comment on the issue thread, the problem is in the test rather than in the library itself.  Sorry that it hasn't been addressed since the issue was filed in 2013 -- it doesn't show up on the platforms we use regularly build for, which are mainly 64-bit, or we would have cleaned it up long ago.

Hi all,

I am preparing the debian package for openexr. I am running in the following issue, when the test suite runs, here is what I get (debian jessie x86/32bits):

[...]
Running testOptimizedInterleavePatterns
Testing SSE optimisation with different interleave patterns (large images)

This is a hard-failure based on an assert(). Is there an actual issue in openexr 2.2.0 ?

 

Thanks much,
