ICG mistakes a function pointer with default value as a variable

[alexlin0]

This line in a class is mistaken as a double by ICG

double (*shaping_func)(double,double) = NULL;

io_src code is created by ICG. The checkpointer will try unsuccessfully, but not fatal, to checkpoint this.

I worked around it by changing the line to this

double (*shaping_func)(double,double){nullptr};

How is this different from how Trick treats normal pointers? If they aren't (**)'d out you'll get badness out of that too. What's different about a function pointer, aside from ICG being wrong about what it is?
