Hi,

I'm getting mad with following problem: The code compiles, but I always get
a segfault and I don't have any clue why. I can't see any differences in my
way of calling mktime and others.

---------------------------------------------------------------------------

#include <iostream>
#include <sys/stat.h>
#include <time.h>

// -1 bei Fehler (z.B.: File not found)
// 0 -> nicht modifiziert
// 1 -> wurde modifiziert
int file_modified_since(char* file, char* date) {
  struct stat* fileattribs;
  time_t last_modification;
  struct tm brokentime;
  time_t datestamp;
  
  stat(file, fileattribs);
  std::cout << "File: " << file << "\n";
  std::cout << "Last Content Change: " << fileattribs->st_mtime <<
"\n"; //time_t
  std::cout << "Last Attrib Change: " << fileattribs->st_ctime << "\n";
  if (fileattribs->st_mtime > fileattribs->st_ctime) {
    last_modification = fileattribs->st_mtime;
  } else {
    last_modification = fileattribs->st_ctime;
  }
  std::cout << "Last Modification: " << last_modification << "\n\n";
  
  std::cout << "Date: " << date << "\n";

  brokentime.tm_year = 104;
  brokentime.tm_mon = 11;
  brokentime.tm_mday = 31;
  brokentime.tm_hour = 12;
  brokentime.tm_min = 15;
  brokentime.tm_sec = 59;
  
  mktime(&brokentime); // segfaults.
  
  return -1;
};
