                    compiler error: in is_base_type, at dwarf2out.c:9968)
           Product: gcc
           Version: 4.8.4

Tarball with reproduction information

When compiling the attached repro.cc without the -g flag, g++ succeeds:

~/gcc_bug [deepthought●] » g++ -std=c++11 repro.cc                              

With the -g flag, g++ hits an internal compiler error:

~/gcc_bug [deepthought●] » g++ -std=c++11 repro.cc -g
repro.cc: In instantiation of ‘struct lambda_visitor<void,
main()::__lambda0::__lambda2>’:
repro.cc:10:8:   required from ‘struct lambda_visitor<void,
main()::__lambda0::__lambda1, main()::__lambda0::__lambda2>’
repro.cc:49:62:   required from here
repro.cc:22:8: internal compiler error: in is_base_type, at dwarf2out.c:9968
 struct lambda_visitor<ReturnType, Lambda1>
