Here is an example of more debugger crashiness while exploring mirrors (SDK at head yesterday, before the revert of the type checking). Modified parseListProperty to be the following, with a breakpoint on the return and I tried to have the debugger evaluate the expression at that line.

(Please see #35009 (comment) for more context)
