Package: openimageio
Version: 1.7.17~dfsg0-1
Severity: normal
Tags: patch
User: [email protected]
Usertags: origin-ubuntu bionic ubuntu-patch
In Ubuntu, the attached patch was applied to achieve the following:
* alignment.patch: Cherrypick upstream fix for ustring::TableRep alignment.
This doesn't immediately expose itself as a problem in the opemimageio
build itself and, indeed, isn't a problem on armhf systems where alignment
issues are trapped and fixed up on the fly (which is some, but not all of
them), however we saw it as a SIGBUS in blender on the Ubuntu buildds,
which don't trap and fix-up alignment errors.
