The real token position is required in case debugger stopped on an exception thrown from AssertAssignable and trying to evaluate an expression which uses receiver. Without token position all local variables (including receiver) are considered out of scope (as frame's token position is out of range). TEST=runtime/observatory/tests/service/regress_48279_test.dart Fixes https://github.com/dart-lang/sdk/issues/48279 Change-Id: Idb6a8e12185367ceac2034269b8f046272384006 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/231748 Reviewed-by: Ben Konyi <bkonyi@google.com> Commit-Queue: Alexander Markov <alexmarkov@google.com>
