// run-pass
// Regression test for Issue #30018. This is very similar to the
// original reported test, except that the panic is wrapped in a
// spawned thread to isolate the expected error result from the
// SIGTRAP injected by the drop-flag consistency checking.

// ignore-emscripten no threads support
