Description

We ran into a problem recently with some bugs that only affected 32-bit builds. Fortunately, Jenkins caught them, but it would be cool if we could get Travis to check them too. Is that viable?

We don't have to necessarily build on a 32-bit platform, just so long as we build somewhere where we can target 32-bit builds, and exceute them.

We can add a few commands to build/run in a 32-bit docker container.

Triaging some tickets not absolutely vital to 0.3.4 release to 0.3.5. These are fine to do in 0.3.4, but they aren't a must.

I think we should clarify what we intend to accomplish with this. With the container approach, it would build 32-bit binaries but not emulate a 32-bit processor, right? I think we would be able to catch some integer limit bugs, but maybe not some more subtle bugs that only appear on true 32-bit hardware.

I think doing 32-bit Linux under 64-bit processors would still be ok.

32-bit macOS would be faster (no docker) but might be slower because MacPorts doesn't have some 32-bit binary packages. (So we'd end up building them from source.) But we should eventually do it, because macOS has slightly different data types then Linux.

These tickets are being triaged out of 0.3.5. The ones marked "035-roadmap-proposed" may return.
