I'm seeing different behavior for stack frames reported from a pause event when breaking on an exception, and from log messages for that same exception. 4 stack frames are reported in the pause event, and 3 in the log message (see attached images). More importantly, the top three frames in the pause event do not provide location information. The corresponding frames do provide location info when reported in the log message. Here's a repro case:
<!DOCTYPE html>
<html>
<head>
<title>test</title>
</head>
<body>
<p id="text"></p>
<script src="packages/browser/dart.js"></script>
<script type="application/dart">
void main() {
print("foo");
int.parse("bar");
print("baz");
}
</script>
</body>
</html>
And the debugger wire traffic (note the scriptId == 0 parts):
