[Bug c++/25365] New: g++ crashes with segmentation fault, when -Wall is active

Hi,

the g++ crashes with segmantation fault, when compiling the following code
snippet with "g++ -c -Wall". It compiles without the "-Wall" option.

#include 

// http://www.oreillynet.com/pub/a/network/2003/10/07/michael_barr.html
// Example 2. An anonymous union allows the compiler to report
// typedef errors automatically 
static union
{
charint8_t_incorrect[sizeof(  int8_t) == 1];
char   uint8_t_incorrect[sizeof( uint8_t) == 1];

char   int16_t_incorrect[sizeof( int16_t) == 2];
char  uint16_t_incorrect[sizeof(uint16_t) == 2];

char   int32_t_incorrect[sizeof( int32_t) == 4];
char  uint32_t_incorrect[sizeof(uint32_t) == 4];

};

it doesn't crash, if I use the union in the code, e.g.:

=8<=
int main() {
void *p;
p = int32_t_incorrect;
return 0;
}
