Status: UNCONFIRMED
Severity: trivial
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org

--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27091
try to compile this using: g++-4.6 -g -std=c++0x x.cpp
Probably wrong syntax/understanding causing SEGV in gcc 4.5 and gcc 4.6
$ g++-4.6 -g -std=c++0x -v -save-temps x.cpp
Using built-in specs.
