Bug ID: 63438
Summary: conditional operator deducing lvalues incorrectly
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: eric.niebler at gmail dot com
Target: i686-pc-cygwin
Problem is with the following code:
int i = 0;
const int j = 0;
static_assert(std::is_same<decltype(true? i : j), int const &>::value, "");
I expect the static_assert to pass. It doesn't. It does with clang. Compiled
with -std=gnu++11.
$ gcc -v
Using built-in specs.
