Bug 326451

Description Francis Giraldeau 2010-09-28 14:50:55 EDT

Build Identifier: 20100218-1602

Under debuggin, named union inside struct displays each possible interpretation of a value:

Name : x
	Binary:110000
	Decimal:48
	Other (Details):48 '0'
	Hex:0x30
	Default:48 '0'
	Octal:060


An anonymous union displays this error: 

Failed to execute MI command:
-data-evaluate-expression ((v2)->).x
Error message from debugger back end:
A syntax error in expression, near `).x'.

It seems that the command sent to GDB is invalid. It should have been (v2)->x



Reproducible: Always

Steps to Reproduce:
Compile and run the following C program : 

#include <stdio.h>
#include <stdlib.h>

struct a {
    union {
        unsigned char x;
        int y;
    } b;
};

struct c {
    union {
        unsigned char x;
        int y;
    };
};

int main(void) {

    struct a *v1 = malloc(sizeof(struct a));
    struct c *v2 = malloc(sizeof(struct c));

    v1->b.x = '0';
    printf("%i\n", v1->b.y);

    v2->x = '1';
    printf("%i\n", v2->y);

    return EXIT_SUCCESS;
}
