Description

The following snippet of code

std::vector<proton::value> array_2 = {nullptr, nullptr, };

compiles, but when run throws the following core:

terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_M_construct null not valid

Program received signal SIGABRT, Aborted.
