Ref-count assertion failure when handling thunks in a unit test #36

Closed Mercerenies closed 6 years ago

Mercerenies commented 6 years ago

The following block of code results in an assertion failure (ptr->ref_count <= 0).

use 'unit-test.

test ::= Module clone.
unit-test TestModule inject (test).
callCC {
  escapable.
  test addTest 'name1 do { return "This is stupid and don't do this.". }.
}.
test runTests.

This block of code is clearly an infinite loop and could possibly overflow the call stack (though I doubt it), but it should certainly not be causing issues with the reference counter.

The bug cannot be reproduced in 4460813, which means it was certainly introduced in 616fa7f, when the thunk warning was added.
