Patch

This seems to fix it. I'm unsure of how recordLinkOffsets()/executableOffsetFor() are supposed to work on thumb2, as they seem to assume that jump origins and destinations are 4-byte aligned, though I might be misunderstanding something, as it looks like this has been working like that since the introduction of thumb2 support.
