[Moved to DR at the November, 2014 meeting.]

Proposed resolution (June, 2014):

This issue is resolved by the resolution of issue 1467.

Date: 2012-10-15.00:00:00

Notes from the October, 2012 meeting:

CWG agreed that the first example should be permitted, but not the second.

Initialization of an array of characters from a string literal is handled by the third bullet of 11.6 [dcl.init] paragraph 16, branching off to 11.6.2 [dcl.init.string]. However, list initialization is handled by the first bullet, branching off to 11.6.4 [dcl.init.list], and there is no corresponding special case in 11.6.4 [dcl.init.list] paragraph 3 for an array of characters initialized by a brace-enclosed string literal. That is, an initialization like

  char s[4]{"abc"};

is ill-formed, which could be surprising. Similarly,

  std::initializer_list<char>{"abc"};

is plausible but also not permitted.
