Bug #: 14523
Summary: Crashing whiling deducing lambda for a free function
template inside a template class.
Product: clang
Version: 3.0
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
AssignedTo: unassignedclangbugs at nondot.org
ReportedBy: n3gb0y at gmail.com
CC: llvmbugs at cs.uiuc.edu
Classification: Unclassified
Created attachment 9646
--> http://llvm.org/bugs/attachment.cgi?id=9646
this is what clang produced.
No idea.
This is my free function template :
template<typename T>
template<typename F>
void Node<T>::applyAll( F f )
{
if ( !hasData() )
return;
f( *m_data );
for( auto e : m_innerNodes )
e->applyAll(f);
}
inside my class template :
template<typename F>
void applyAll( F f );
also my main():
tree.applyAll( [] ( int &n ) { std::cout << n << std::endl; } );
and what clang told me :
main.cpp:19:35: error: use of undeclared identifier 'n'
[] ( int &n ) { std::cout << n <<
std::endl; }
