[Vivian Huang]

Hello Daniel Marjamäki,

I compiled cppcheck2.8 on ubuntu16.04 using "make MATCHCOMPILER=yes FILESDIR=/usr/share/cppcheck HAVE_RULES=yes CXXFLAGS="-O2 -DNDEBUG -Wall -Wno-sign-compare -Wno-unused-function"" command encounterd one compiling error, can you please help me out?

Unfortunately I can't reproduce. I tried with ubuntu 16.04 in a docker container.

but well does it compile properly if you change the code:

functions = {};

to:

functions;
