Bug ID: 15365
Summary: Capturing a const reference parameter by value in
lambda fails to correctly generate
constructor/destructor calls of captured value
Product: clang
Version: trunk
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: release blocker
Priority: P
Component: C++11
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Created attachment 10082
--> http://llvm.org/bugs/attachment.cgi?id=10082&action=edit
Reproduces the bug
Compile attached file with
clang++ -std=c++11 -stdlib=libc++ TestFunctional.cpp -o TestFunctional
The relevant function:
void Capture(std::function<void (CDispatchTypeTag *)> const &_Function)
{
//auto Function = _Function; // Uncomment this and it works
auto fTest
= [_Function]()
{
_Function(nullptr);
}
;
}
The destructor and copy constructor is not called the correct number of times
unless the line above is uncommented.
