Bug #: 13797
Summary: std::__1::__function::__func::destroy invokes
destructor multiple times
Product: libc++
Version: unspecified
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
AssignedTo: [email protected]

Classification: Unclassified
First off - I would consider explicitly invoking a destructor very bad style.
Regardless - destroy may and is (when you do moving of function) called
multiple times - which (correctly) crashes for some compilers.
For now I patched the explicit destructor calls to __compressed_pair in destroy
and destroy_deallocate with a boolean guard.
The more correct solution IMO would be to implement a destroy in
__compressed_pair, too, which checks for multiple invokation.
