Description LI Daobing 2006-04-04 05:41:28 UTC

when compile following file[1] with option `-Wall', it will give a
warning[2]. g++-4.0 do not has this problem. I don't think this
warning is proper.

// begin array2.cpp
#include <tr1/array>

int main() {
  std::tr1::array<int, 2> foo = {0, 1};
  return foo[1];
// end

array2.cpp: In function 'int main()':
array2.cpp:4: warning: missing braces around initializer for 'int [2]'

  array.ii.bz2 is in attachment, uncompress it. then use
  'g++-4.1 -Wall -c array.ii' to reproduce this bug.
Comment 1 LI Daobing 2006-04-04 05:41:28 UTC
  work around, the following code will not generate warning with
  '-Wall', but it looks strange.

// begin
#include <tr1/array>

int main() {
  std::tr1::array<int, 2> foo = {{0, 1}};
  return foo[1];
