#11696 closed Bugs (fixed)

variant& operator=(variant&& rhs) never noexcept under clang

Reported by: Tobias Reh <treh@…> Owned by: Antony Polukhin
Milestone: Boost 1.62.0 Component: variant
Version: Boost 1.57.0 Severity: Problem
Keywords: Cc:

Description

The noexcept specification for variant's move assignment operator is compiled only conditionally under the following preprocessor switch: 

#if !defined(__GNUC__) || (__GNUC__ != 4) || (__GNUC_MINOR__ > 6)

clang 3.6 defines the gnu macros as if it were gcc 4.2. Therefore the above switch evaluates to false and the noexcept specification is not visible under clang.
