gcc -fvisibility problem

I have the problem described here:

http://gcc.gnu.org/wiki/Visibility

Exception class exported from shared library cannot be caught when used outside of the library, and the program terminates. I added __attribute__((visibility("default"))) to the class de开发者_StackOverflowclaration:

class  __attribute__((visibility("default"))) MyException
{
    ...
};

But this doesn't help. Client executable does not catch this exception. gcc version is 4.4.1, used in the Linux OS.

For future reference: this was not visibility problem. I got an answer here: Exceptions are not caught in GCC program
