Ah, but you did you understand what nm was telling you?
$ nm /usr/local/lib/libiconv.so.6.0 | grep aliases2
0000d5c0 t aliases2_lookup
$

Each symbol name is preceded by its value (a blank field if the symbol is
undefined) and one of the following letters:
...
T text segment symbol
...
If the symbol is local (non-external), the type letter is in lower case.
The output is sorted alphabetically.

So, aliases2_lookup is local to libiconv.so and can't be accessed
externally. To put it another way, the program is peeking where it
shouldn't. Bad Programmer, no cookie! Go yell at the that project...
