I don't see this problem with clang-2.8.
Why clang-3 does not allow code like (I don't have clang-3 to check)?
int main()
{
unsigned char uc = 10;
char c[2] = { uc , 1 };
}
Is this really error, why the compiler does not cast?

Is this the same error all over?
Can you send me the list of such locations or a patch so I'll
be able to commit it to trunk and ask permissions to merge to release
branch.
