I have seen this "problem" before, well, it isn't really a problem I guess.
I'm not sure of the gcc compiler options, but....
On the Microsoft compiler if you specify the option "/Gy" it separates the
functions within the object file, that way you don't load all the
functions from the object if they are not needed.
If, however, you create a function with the same name as another function,
and one is declared in an object compiled with the "/Gy" option, and the
other's object file is not, then if you also use a different function or
reference variable in the object file compiled without the "/Gy" option,
then the conflicting function will probably be used. Make sense?
I would suggest using macro to redefine snprintf and vnsprintf to avoid
the issue:
#define snprintf pg_snprintf
#define vnsprintf pg_vnsprintf
