#16066: internal error: PAP object entered! ----------------------------------------+---------------------------------- Reporter: dnspies | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.4.4 Keywords: | Operating System: iOS Architecture: Unknown/Multiple | Type of failure: Runtime crash Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: ----------------------------------------+---------------------------------- While trying to debug why my test didn't seem to be running, I got an internal error (below). After a clean and rebuild it happened again so it's not a flake. Unfortunately I don't know what's causing it so I can't produce an MWE, but I can link to the project and commit on GitHub: https://github.com/dspies- leapyear/persistwrap/tree/885a079923cb3eefb24db344f5e2fddee9fab425 Just run the test with: {{{ stack test persistwrap:persistwrap-test }}} {{{ Progress 9/10: persistwrap-0.1.0.0test/Driver.hs test_widget_schemas: persistwrap-test: internal error: PAP object entered!
