// This test ensures that check::LiveSymbols is called as many times on the
|
|
// path through the second "return" as it is through the first "return"
|
|
// (three), and therefore the two paths were not merged prematurely before the
|
|
// respective return statement is evaluated.
|
|
// The paths would still be merged later, so we'd have only one post-call for
|
|
// foo(), but it is incorrect to merge them in the middle of evaluating two
|
|
// different statements.
