1490. List-initialization from a string literalSection: 9.5.5 [dcl.init.list] Status: CD4 Submitter: Daveed Vandevoorde Date: 2012-03-29[Moved to DR at the November, 2014 meeting.]
Initialization of an array of characters from a string literal is handled by the third bullet of 9.5 [dcl.init] paragraph 16, branching off to 9.5.3 [dcl.init.string]. However, list initialization is handled by the first bullet, branching off to 9.5.5 [dcl.init.list], and there is no corresponding special case in 9.5.5 [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.
Notes from the October, 2012 meeting:
CWG agreed that the first example should be permitted, but not the second.
Proposed resolution (June, 2014):
This issue is resolved by the resolution of issue 1467.
