floating point co-processor fault at adress 0040914c

Hello guys

I´m running a program which use the subroutine FOUR1 to make the Fast Fourier Transform of a complex function. I don´t know why but in one of that calls to the subroutine appears that error and I dont really know what is about. I have read that could be a division by zero, but that is not my case. any suggestions?

Thanks

It´s already solved. It was just a huge number so the program broke down in the subroutine.
