Teensy Build Errors with std::vector

Hello
I get errors during build when I use std::vector, for example:
std::vector a {1,2,3,4};

Here is the log:

If I remove the std::vector type variables the build is successful, I would like to use vectors so that I could use binary_search functions in CPP algorithms library.
