Hi all!

First of all hello everybody! because I've just joined
the list. I've had a lok into the Mailing list archive and I've seen
that this error has happened before to other people but each time the
solution was different and I haven't found the answer to my specific
case so here we go!


I'm just trying to read a .data file and create a .xls file to use
with excel; for that I've created the next simple program:

#include <stdio.h>

main (int argc, char* argv[])
{
    FILE *f1, *f2;


    char *file_name;
    int num_compressors = 0;
    int num_files = 0;
    int numC = 0;
    char *out_file;
    char *aux;
    char *ctime;

     if(argc != 2)
    {
      fprintf(stderr, "Use: %s nameOfFile\n", argv[0]);

      exit(1);
    }

     // Open source file
     if ((f1 = fopen(argv[1],"r")) == NULL){
    fprintf(stderr, "Can't open %s\n", argv[1]);
    exit(1);
      }

      fprintf(stderr, "%s opened\n", argv[1]);


      fscanf(f1,"%d",&num_compressors
);
      fprintf(stderr, "Number of compressors: %d\n", num_compressors);
      fscanf(f1,"%d",&num_files);
      fprintf(stderr, "Number of files: %d\n", num_files);


      do{
                  // THE PROBLEM SEEMS TO BEGIN HERE
           fscanf(f1,"%s",out_file);
           fprintf(stderr, "Name of compressor: %s\n", out_file);

       out_file = strcat(out_file, ".xls");
           fprintf(stderr, "Read name of the new file: %s\n", out_file);
           // Create new .xls file
          f2 = fopen (out_file, "w");

          if (f2==NULL){
             fprintf(stderr, "Can't open %s\n", out_file);
             exit(1);
          }

                fscanf(f1,"%s",file_name);
                fprintf(f2, "%s\t", file_name);

                fscanf(f1,"%s %s", aux, ctime);
                fprintf(f2, "%s\t", ctime);
               numC++;
        }while (numC < num_compressors);

  fclose(f1);
  fclose(f2);


}


The test .data file is called pruExcel.data and consist of:

1
1

gzip

to_mm_24.bin

real    0m0.614s
user    0m0.499s
sys    0m0.015s


And the output :


$ ./oExcel pruExcel.data
pruExcel.data opened
Number of compressors: 1
Number of files: 1
      7 [main] oExcel 2988 _cygtls::handle_exceptions: Error while dumping state
 (probably corrupted stack)
Segmentation fault (core dumped)

I'm working with Windows XP and CYGWIN_NT-5.1,

any idea would be appreciated!
Thanks!
