Hello!
I have discovered even worse problem -- specifying a full 32-bit enum
value like `*0x80000001*' makes GDB unhappy.
It complains `Cannot access memory at address 0x0' when I am trying to
print the value of that enum type.
$ cat a.c
enum some_t
{
x = 0x80000001,
y = 0x80000002,
z = 0x80000003
};
int
main (void)
{
return 0;
}
$ gcc -g a.c
$ gdb a.out

Thanks.
