[Bug c++/20140] New: template function complains about "char-array initialized from wide string"

[rwxr-xr-x at gmx dot de]

Hello,

this is my code:

template<typename T> void foo() {
    unsigned char s[] = "";
    (void)s;
}

int main() {
    /* removing either of the calls below makes the error disappear */
    foo<int>();
    foo<char>();
}

Compiling this program with g++[0] results in
try.cc: In function `void foo() [with T = char]':
try.cc:9:   instantiated from here
try.cc:2: error: char-array initialized from wide string

I think this is wrong because "" isn't a wide string. The error disappears
when I remove "unsigned" from the declaration of s, or when only a single
foo<T> is instantiated. The actual types don't matter; my original code
used function pointers.

HTH, Lukas
