What is surprising about it?

The result of typeinfo::name() is implementation-defined, don't expect
to get the same result when you use different compilers, or different
versions of the same compiler.  G++ and egcs have chosen to return the
string produced by its own symbol name mangling mechanism.  `i' refers
to the integer type, and `1A' refer to a class name of length `1',
namely, `A'.
