The Fortran compiler now correctly deallocates coarrays that are allocated within a team block. Previously, these coarrays were not automatically deallocated before the END TEAM statement, violating the F2018 standard. This change ensures compliance by tracking team contexts and stashing allocate expressions for automatic deallocation.
