Steps to reproduce:
- create simple application using the following source:

int main(int argc, char**argv) {
    union{
        int value;
        unsigned char ch[4];
    };
    value = 0xabcdef01;
    int val = 0;
    for(int i=0; i<4; i++){
        val = ch[i];
    }
    return 0;
}

- start debugging
- open Variables
Result: Neither 'value' nor 'ch' are displayed in Variables. Watches give <text variable, no debug info> and <data
variable, no debug info> correspondingly.
