 Bug Report for GCC:
 -------------------
 Problem : Compiler dies with "cc1 got fatal signal 6"

 1.) Version : gcc 1.32
 -----------

 2.) Input Program :
 -----------------

#include <stdio.h>  
#include <math.h> 

float s_depth(fft_size, samp_rate, nom_shot_depth)     

unsigned long fft_size;   
float  samp_rate, nom_shot_depth;  
{      
double delta_period, bubble_pulse_period, w_one_third, shot_depth;  
float binwidth, bp_freq;
short span;  
w_one_third = pow(1.87, 0.3333333333);  
   
bp_freq = (float)1.0 / ((4.34 * w_one_third) / 
                        (pow(((nom_shot_depth * 3.28084) + 33),(5.0/6.0))));  
binwidth = samp_rate / (float)fft_size;  
span = 1.0 * bp_freq / binwidth; 
if ( span < 5 ) span = 5;

delta_period = 2.0 / samp_rate;

bubble_pulse_period = delta_period ;   

shot_depth = (float)pow((4.34 * w_one_third / bubble_pulse_period), 
                        (6.0 / 5.0)) - 33.0;   

return((float)shot_depth);     
}
