How reproducible:
Always

Steps to Reproduce:

#include <iostream>
#include <fontconfig/fontconfig.h>

int main() {
  FcPattern *pat, *match;
  FcResult result;
  char *family;
  char *file;
  int index;

  FcInit();
  pat = FcPatternCreate ();
  FcPatternAddString (pat, FC_FAMILY, (const FcChar8*)"open symbol");
  FcPatternAddInteger (pat, FC_WEIGHT, FC_WEIGHT_NORMAL);
  FcPatternAddInteger (pat, FC_SLANT, FC_SLANT_ROMAN);
  FcConfigSubstitute (NULL, pat, FcMatchPattern);
  FcDefaultSubstitute (pat);
  match = FcFontMatch (NULL, pat, &result);

  FcPatternGetString (match, FC_FAMILY, 0, (FcChar8**)&family);
  FcPatternGetString (match, FC_FILE, 0, (FcChar8**)&file);
  FcPatternGetInteger (match, FC_INDEX, 0, &index);

  std::cout << family << std::endl;
  std::cout << file << std::endl;
  std::cout << index << std::endl;
}
