<pre>Since r222551 ("Enable ActOnIdExpression to use delayed typo correction for
non-C++ code when calling DiagnoseEmptyLookup"), the following (invalid) C++
input has started causing clang to crash. I've verified that it produces the
expected compilation errors without crashing in r222550 but is still crashing
as of r222849:
// begin
int x = { y[
// end
$ clang -c small_ice.cpp -fsyntax-only -target x86_64-unknown-unknown
small_ice.cpp:3:7: error: expected expression
// end
^
small_ice.cpp:3:7: error: expected ']'
small_ice.cpp:2:12: note: to match this '['
int x = { y[
^
