Comment 2 for bug 1707931

Issue #2 was introduced by 685e6b093730b5f3bd590409e27a4e87b1c03111 between 3.15.0.1 and 3.15.0.2. The 3.14 series uses 'int' on all targets, and thus doesn't trigger send_err().

Issue #1 is is present in the 3.14 series. The first unguarded call to send_err() was present in 3.14.0, the second was added prior to 3.14.7.
