Rcpp test coverage with c++11

[seninp]

I used covr to collect the test coverage for my R/Rcpp code and everything worked just right. But when I bumped to C++ 11 (I need to use unordered maps and few other things), I can no longer get the test coverage for cpp files. Specifically things changed after I added "SystemRequirements: C++11" to my project DESCRIPTION file. Is there any way to see the test coverage for cpp files whilst using C++ 11?

Do you have an example repository where this is failing? It will be easier to diagnose the issue with an concrete example.

Thank you! The repository is jmotif-r. The first build where it didn't collect the coverage is this e65e3c5 the last success is this one 3792b10.

Last days I spent much time tinkering with C++ versions and flags, could be difficult to navigate through commits, sorry.
