Possible to debug resulting application?

I’ve gotten a build completing here but unfortunately it segfaults on launch. I can see the single exception that’s causing the failure, but no way to get a stacktrace or begin debugging this issue. Is there a way to produce a debug binary?

Start by reproducing the completed build and launch segfault described in the issue, then inspect the build configuration and resulting binary options. The work is done when a debug binary can be produced and used to obtain a stack trace for the failing application.
