Your question contained references to GTK+'s C interface. If that means that you are using C or C++ for your program, those languages do not have a syntax for nested functions, so what you say does not really make sense. If you are simulating them in C++ using static methods of a nested struct, in C++98 you have undefined behaviour if you try to use them as a callback, because static member functions of classes with local scope have no linkage (this follows because §3.5/5 of the standard provides that a member function of class scope has external linkage if the name of the class has external linkage, which it doesn't in the case of local nested structs, and §3.5/8 provides that "Names not covered by these rules have no linkage"). So it is most likely a misunderstanding on your part rather than a compiler bug, but you would need to post your code to be sure.
