Subject: Fix the following bug...
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=fd8b4a4b29a2b9d662d0c9a92c1eebd83160b10b;p=clang

Fix the following bug...

unsigned char asso_values[] = { 34 };
int legal2() {
  return asso_values[0];
}

The code that creates the new constant array type was operating on the original type.

As a result, the constant type being generated was "unsigned char [1][]" (which is wrong).

The fix is to operate on the element type - in this case, the correct type is "unsigned char [1]"

I added this case to array-init.c, which clearly didn't catch this bogosity...
