These are just mangled globals that define types in C++ (I have no
idea about other languages).

$ c++filt _ZTIi
typeinfo for int

$ c++filt _ZTIPKc
typeinfo for char const*

So, if the typeinfo for the exception thrown is the same (ex. _ZTIi),
the comparison match because they point to the same global.
