I was about to mark this as Invalid with a comment that Walter has said that this is not going to be fixed (the error is correct, that stack /did/ get blown)... Then I noticed Walter Reported it. <g>

Not so, the bug is that there is no error message. For the first case, there's no error message, for the other cases, there's an error message on Windows, but not on Linux.

BTW, (1) the text is mine -- I forwarded it to Walter as part of a list of crashes.
(2) if it were not to be fixed, it should be WONTFIX rather than INVALID.
