Bug ID: 31623
Summary: Regression in std::vector initialization in clang++
3.9.x
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: d...@mapbox.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
clang 3.9.0 and 3.9.1 refuse to compile code that worked in 3.8.1:
```
#include <mapbox/geometry/polygon.hpp>
int main() {
mapbox::geometry::polygon<double> polygon = {{ {{ { 0, 0 }, { 0, 45 }, {
45, 45 }, { 45, 0 } }} }};
}
```
mapbox/geometry/polygon.hpp can be found here:
https://github.com/mapbox/geometry.hpp/blob/master/include/mapbox/geometry/polygon.hpp
That errors with: `error: no matching constructor for initialization of 'const
mapbox::geometry::linear_ring<double, std::vector>'.
However this works:
```
Polygon<double> polygon = { {{ { 0, 0 }, { 0, 45 }, { 45, 45 }, { 45, 0 } }} };
```
