It works OK on 10.6, 10.7.

It would make sense to try building with a different compiler.

Developers responded with a link to ​https://forums.wxwidgets.org/viewtopic.php?f=19&t=38397 and some additional comments. I'll attempt another rebuild.

The latest version now fails with

Reported again in #51233. These might be two different problems, but it doesn't make much sense to have two tickets opened as long as the build fails anyway on anything >l 10.9.
