The test emphazing the bug.

Gcc fail to parse a try/catch block in a lambda expression.

It's very strange, we found a way to get around the problem by taking the
exception_ptr by reference explicitly.

Bug reproduced on three machines (uname -a):

I'm compiling with:

with the same command line: -v -std=c++11 -save-temps -W -Wall ./try-catch.cc
