Some tests are failing on my mac with Matlab 2020b. In particular, I get

Running unconstrained_tests
ERROR in validate_data: Missing vector l
ERROR in osqp_setup: Problem data validation.

Error occurred in unconstrained_tests/test_unconstrained_problem and it did not run to completion.

@gbanjac @goulart-paul could you please double check if it happens for you as well?

https://github.com/oxfordcontrol/osqp/pull/283 adds this new check:

  if (!(data->l)) {
# ifdef PRINTING
    c_eprint("Missing vector l");
# endif
    return 1;
  }

Note that unconstrained problems have empty l and u.

This was introduced in https://github.com/oxfordcontrol/osqp/pull/215. I fixed it

Tests run on my macbook now.
