OS: Linux
Status: NEW
Severity: normal

MWE I could build
Find attached the minimum working example I could think. gcc version 4.6.3
provides the following message:
clang_report1.cpp: In member function ‘T1 function_broken(T1&)::<anonymous
struct>::method()’:
clang_report1.cpp:10:14: error: use of parameter from containing function
clang_report1.cpp:7:6: error: ‘T1& value’ declared here
As I could only attach one file, the associated script
(/tmp/clang_report1-hJDYmI.cpp) is:
/usr/bin/clang -cc1 -triple x86_64-pc-linux-gnu -emit-obj -mrelax-all
-disable-free -disable-llvm-verifier -main-file-name clang_report1.cpp
