Try moving the line

bool cl_inhibit_floating_point_underflow = true;

inside the function main, without the bool, so the first three lines look like:

int main()
{
cl_inhibit_floating_point_underflow = true;

Yes, indeed that works! Also for functions called from main().

I almost tried this, but with the bool declaration...

Thanks a lot!

I wonder if section 12.2 of the manual should be modified?

The behaviour maybe depends on compilers and systems.

By the way, I think it most of the time is a bad idea to turn on this

option. Usually underflow is a signal that some lowprecision

variables have contaminated your calculation.
