typeinfo and exceptions

[Tim Janik]

hi all.

i really fail to see what i'm doing wrong in the following code:

struct Exception : std::exception {
   Exception (const char *format, ...) __attribute__((__format__ (__printf__, 2, 3)));
   [...]
};
struct Obj {
   Obj () { throw Exception ("%s: error", typeid (this).name()); }
};
try { Obj a; } catch (std::exception &e) {
   printf ("exception: what(): %s\n", e.what());
}

it does however produce garbage (with 3.3 and 3.4) instead of Obj's typename:
exception: what(): 44`l$@: error

i have attached a full test case with 2 throw statements that
will both produce a garbage typename. i'm not sure this isn't
a compiler bug, so any help is apprechiated.
