Two maps are created. Iterators from second map are used for insertions in the
first.

$ scan-build g++ -std=c++1z wrong_iterator.cpp 
scan-build: Using 'local/tmp/clang/bin/clang' for static analysis
scan-build: Removing directory '/tmp/scan-build-2015-12-08-154917-8614-1'
because it contains no reports.

Example taken from the talk "CppCon 2015: Herb Sutter "Writing Good C++14... By
Default" at 1:09:13 (a Microsoft static analysis tool was demonstrated that is
supposedly able to catch this bug)</pre>
