Description Jörg Pfähler 2011-08-09 11:21:14 UTC
Version:           git master (using KDE 4.7.0) 
OS:                Linux

in the following code kdevelop classifies iter as an "int":

std::vector<char> v;
for (auto iter : v);

This happens independent of the type of the vector (I discovered it with std::shared_ptr).

Reproducible: Always

c++2011 support: proper type deduction in auto range-based-for

for c-arrays we take the element type
for all other types we look via ADL for begin(listType)
and then dereference the return type of that function

See 6.5.4 in the C++2011 spec

Moving all the bugs from the CPP Parser. It was not well defined the difference between it and C++ Language Support and people kept reporting in both places indistinctively
