[Tinycc-devel] Fwd: TCC VLA bug?

[Stefanos]

With `gcc -std=c99` and `gcc -std=c11` I get the - identical in both cases - 
following output:

   1   2   3   4   5
   6   7   8   9  10
  11  12  13  14  15
  16  17  18  19  20

  21  22  23  24  25

  51  52  53  54  55
  56  57  58  59  60

   1   2   3   4   5   6   7   8   9  10  11  12  13  14  15  16  17  18  19  20

With `tcc -std=c99` though and `tcc -std=c11` I get completely different 
results:

For some reason, it gives me the impression it seems '21' as `2+1` thus '3', 
`2+2` thus '4', and so forth; I could be wrong though...
