Build fails (OS X, master, commit 27dc9000)
A clean build of the current master fails for me. The error is:
/Users/lvi/dev/MuseScore/libmscore/instrument.h:209:61: Constexpr variable cannot have non-literal type 'const std::initializer_list'
As I am unfamiliar with this part of the code, I am not fixing this myself. It does block my progress :-(.
