Hello,

 

I have to call a function from the objective function and something extrange happens because when I call this function the error appears and it disappears when I take out the function.

 

Could anyone help me, please?

 

Regards

Hello,

Could anyone help me? I am trying to use galib with a c++ code but I only get a segfault. I tried to analyse it with valgrind and I can see the following:
