Why segmentation(coredump) in the following code in C?

hi
I have a method which returns char*. In this method am using switch case. I am getting segmentation error in case 49 and my code is

Code:

case 49:
          if(intFlag == 0210)
          {
                iiIDCode = atoi(getsubstring(sReq,262,2));
                l = atoi(getsubstring(sReq,26+2+iiIDCode,3));
                iiTemp = 26+2+iiFIDCode+l+3;
                j = atoi(getsubstring(sReq,iiTemp,3));
                k  = atoi(getsubstring(sReq,iiTemp+j+3,3));
                fprintf(fp,"\nCurrency Code Transaction:\t\t[%s]",getsubstring       (sReq,iiTemp+j+k+3+3,3));
                strcat(cRes,getsubstring(sReq,iiTemp+j+k+3+3,3));;
          }
         else if(intFlag == 110)
         {
          }   
break;

getsubstring is a method am using to substring the string and it is working fine. If i remove if and else part it is working fine but if i add if else condition in case 49: it is throwing error Segmentation Coredump. Why? What could be the error? How to solve this?
Thanks

djvu2hocr

DJVU2HOCR(1)							 djvu2hocr manual						      DJVU2HOCR(1)

NAME

       djvu2hocr - DjVu to hOCR converter

SYNOPSIS

       djvu2hocr [option...] djvu-file

       djvu2hocr {--version | --help | -h}

DESCRIPTION

       djvu2hocr converts hidden text from a DjVu file to the hOCR[1] format.

OPTIONS

   Text segmentation options
       --word-segmentation=simple
	   Use the same word segmentation as found in the DjVu file.

	   This is the default.

       --word-segmentation=uax29
	   Use the Unicode Text Segmentation[2] algorithm to break lines into words, possibly fixing word segmentation found in the DjVu file.

   Other options
       --version
	   Output version information and exit.

       -h, --help
	   Display help and exit.

PORTABILITY

       djvu2hocr uses a custom extension to hOCR to retain characters which cannot be directly represented in an HTML/XML document. For example,
       control character BEL (^G, U+0007), is converted into the following HTML chunk: <span class="djvu_char" title="#x07"> </span>
