I'm not sure if this is a bug in the darwin code for shiny, a new bug introduced with the recent changes to signal handling, or an older bug that I've somehow tickled.
I can reproduce this consistently by running e.g. golang.org/x/exp/shiny/example/tile, and clicking. The error message varies between "signal: segmentation fault" and "Segmentation fault: 11".
Running with -race does not report any data races.
The crash was introduced by this commit: golang/exp@bb37e7d (found using git bisect). I can also reproduce the crashes with older versions of Go, so I think the bug probably lies somewhere in that change.
