Hi all,
I’ve tried to port my program that used v1.5r1 to v2.0r0 (and also to a new version of gcc), and I got the following error while compiling:

I'm running Ubuntu Artful Aardvark, gcc 7.2.0 and compiling to c++11 standard.
The benchmark program (cavity3d) builds fine for me. Apparently, that's because these templates only result in an error when they are instantiated with bool, and this doesn't happen in the benchmark.
UPD: I fixed it by specializing the template for bool. Some quick testing shows that it doesn't break anything obvious, at least in my usecase.
[code="cpp"]
template<>
void MultiNTensorField3D<bool>::allocateFields() {
std::vector<char> iniVal(this->getNdim());
std::fill(iniVal.begin(), iniVal.end(), bool());
allocateFields((bool *) &iniVal[0]);
}
