[Bug 1338254] [NEW] internal error on lambda as argument

[Victor-Nicolae Savu]

Public bug reported:

1) The release of Ubuntu I am using:

$ lsb_release -rd
Description:	Ubuntu 14.04 LTS
Release:	14.04

2) The package version:

$ apt-cache policy g++
g++:
  Installed: 4:4.8.2-1ubuntu6
  Candidate: 4:4.8.2-1ubuntu6
  Version table:
 *** 4:4.8.2-1ubuntu6 0
        500 http://ch.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages
        100 /var/lib/dpkg/status


3) What I expected to happen:

I expected the source file "test.cc" to compile correctly, using the
compiler command:

g++ -std=c++1y test.cc

4) What happened instead:

Compiler output:

test.cc: In instantiation of ‘struct S<int>::__lambda0’:
test.cc:15:8:   required from here
test.cc:18:8: internal compiler error: in tsubst_copy, at cp/pt.c:12125
   B b{[this]() { foo(); }};
        ^
