<pre>Using r222680
int main(int argc, char *argv[])
{
float x = 1.0f;
x = (float) arst;
}
This produces the unhelpful error:
error: operand of type '<dependent type>' where arithmetic or pointer type is
required
1 error generated.
which doesn't even include a line number.
clang 3.4 produces the correct error:
clang_warning_bug.c:5:17: error: use of undeclared identifier 'arst'
x = (float) arst;
^
1 error generated.</pre>
