Decoding errors on Intel Mac using SIMD (Debug builds only)

[fnordware]

Building with the default configuration on an Intel Mac, I get an error when running ojph_expand on a file I had created using ojph_compress. The error is: ojph_codeblock.cpp:219: Error decoding a codeblock.

If I use OJPH_DISABLE_SIMD I get no error.

Hi Brendan,

Thank you for filing this issue.

I think you discovered that the problem also exists with OpenJPH Tests.

I do not have access to a Mac in the foreseeable future. I will try to see if I can find another way.

Thank you.

Kind regards,
Aous

@aous72 Have you considered EC2 https://aws.amazon.com/ec2/instance-types/mac/ ?

I have some good news: this issue only appears in Debug builds, not Release. So I don't know how much of a problem it really is. Here's a screenshot of the error happening in the debugger, if it helps:

I could let you remote into my Mac if you want to poke around a bit. Not sure how well it will work all the way to Australia though.
