Consider a test-case compiled without debug info, containing:
...
char a = 'a';
char *
a_loc (void)
{
return &a;
}
...
We get:
...
(gdb) p (char)*a_loc ()
Cannot access memory at address 0x10
...
There's a bug in unop_ind_base_operation::evaluate that evaluates
"(char)*a_loc ()" the same as:
...
(gdb) p (char)*(char)a_loc ()
Cannot access memory at address 0x10
...
Fix this by instead evaluating it the same as:
...
(gdb) p (char)*(char *)a_loc ()
$1 = 97 'a'
...
Tested on x86_64-linux.
