For code such as:
int f(int x) {
if (int foo = f(bar)) {}
return 0;
}
Clang produces the following error messages:
paren_imbalance.cc:2:19: error: use of undeclared identifier 'bar'
if (int foo = f(bar)) {}
^
paren_imbalance.cc:2:26: error: expected ')'
if (int foo = f(bar)) {}
^
paren_imbalance.cc:2:6: note: to match this '('
if (int foo = f(bar)) {}
^
The second error is incorrect. This patch will stop Clang from producing an error on parenthesis imbalance during error recovery when there isn't one.
