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
