source files, in the first one I have written the implementations of the functions, and in the second one (which is my main), I call and execute them. Though, at one point I get an error message saying Floating point exception (core dumped) and the program stops. As I said there are lots of lines of code, therefore, I'm not able to post my whole source code here, though I will post the most relevant

parts, and where error occurs. My error occurs when I try to call this function (below you can find its implementation): void chest_first(Complex* FFTInput, Complex* IFFTOutput, Complex* HFirst) { int i; for(i = 0; i < 64; i++) { HFirst[i].real = FFTInput[i].real / IFFTOutput[i].real; HFirst[i].imag = FFTInput[i].imag / IFFTOutput[i].imag; } } In this case Complex, is a type definition that I have defined. typedef struct { int real, imag; } Complex; Here is the part from the main, where this function is called. Complex HFirst[64]; if((strcmp(channel, "LS") == 0) || (strcmp(channel, "ls") == 0)) { if(i == 1) chest_first(fft_input, ifft_bpsk_output, HFirst); . . . } I have earlier called some other function, which put values to fft_input and ifft_bpsk_output, which are both Complex arrays with 64 elements. c exception floating-point coredump floating-point-exceptions share|improve this question asked Jun 25 '13 at 14:22 user1726549 6 IFFTOutput[i].real (or .imag) is 0. (Or -1, and the dividend is INT_MIN is another possibility on some platforms.) Confusingly, an integer division by 0 gives rise to SIGFPE. –Daniel Fischer Jun 25 '13 at 14:25 @Daniel Fischer, your insightful comment about the quirks of integer division and causing SIGFPE deserves an answer posting. –chux Jun 25 '13 at 14:49 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted You're probably
