Bug #: 14274
Summary: double free or corruption with lamba expression in
template using libstdc++
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++11
AssignedTo: unassignedclangbugs at nondot.org
ReportedBy: markus at trippelsdorf.de
CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
Classification: Unclassified
Consider (testcase from http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55223):
markus at x4 tmp % cat lamb.cpp
#include <iostream>
#include <functional>
template<typename T> struct C
{
static T test(std::function<T(int)> f = [](int i){return i;})
{return f(42);}
};
int main()
{
C<int>::test();
return 0;
}
markus at x4 tmp % clang++ -std=c++11 lamb.cpp
