Bug ID: 104013
Summary: Constructor for std::vector<std::any> with single
element initializer list defaults to length
construction
Product: gcc
Version: 8.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: trekie10b at gmx dot de
Target Milestone: ---
std: c++17
The following code initializes a vector of int with one element (5):
std::vector<int> vec_test_int = std::vector<int>({5});
The following code, however initializes the vector with 5 empty std::any
objects:
std::vector<std::any> vec_test_any = std::vector<std::any>({5});
As per the standard (ยง13.3.1.7), the initializer_list constructor overload of T
(std::any) should take precedence over that of std::vector, as it does in the
first case.
