Running fc-list in gdb leads to the following problem:

At garnome-0.21.0/misc/freetype/work/freetype-2.1.3/src/gzip/ftgzip.c
lines 449-471:

    for (;;)
    {
      FT_ULong   delta;

      delta = (FT_ULong)( zip->limit - zip->cursor );
      if ( delta >= count )
        delta = count;

      FT_MEM_COPY( buffer, zip->cursor, delta );
      buffer      += delta;
      result      += delta;
      zip->cursor += delta;
      zip->pos    += delta;

      count -= delta;
      if ( count == 0 )
        break;

      error = ft_gzip_file_fill_output( zip );
      if (error)
        break;
    }

we have an infinite loop:

(gdb) n
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) n
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) n
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb) 
3: delta = 0
2: count = 6
(gdb)
