Error when running executable after the code correctly compiled in C++11

I have a long C++ code that used to work 2 years ago and now I want to use it again with some slight modification. The code compiles without issues, however, upon running the executable, which should output a file with some numerical data, I get the following error

libc++abi.dylib: terminating with uncaught exception of type
std::__1::basic_string<char, std::__1::char_traits<char>,
std::__1::allocator<char> > 
Abort trap: 6

I don't think the problem is with the code itself, but with some compiling option on my computer. I'm using OSX 10.13.6 and I'm simply compiling using

g++ -std=c++11 <filename> -o <executable_name>

The code is long and it basically just makes some calculations and then outputs a .dat file, I wouldn't know what portion of the code to include because the error doesn't tell me anything useful. If someone could guide me to what's the problem it would be very helpful.
