ice when compiling included lambda pattern (internal compiler error: in is_base_type, at dwarf2out.c:9968)

[Samuel Just]

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

ice.tgz is attached with
- error.out has the above output
- repro.cc has the source which triggers the ice
- preprocessed_source.cc has the preprocessed source
- the crash file

I reported the bug upstream: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=72779

It seems to be fixed by 5.3.1.
