#1922 closed Bug (fixed)

Uninitialized variable in sbcapr.F90

Description

Context

If ln_apr_dyn is false, then we do not call sbc_apr and we do not read namelist namsbc_apr, and thus we do not initialize ln_apr_obc

However, bdydta.F90 makes use of ln_apr_obc, and this can lead to a segfault

Analysis

We must not use uninitialized vars

Fix

Two choices:
A) Add IF ( ln_apr_dyn ) THEN ... ENDIF around the code in bdydta.F90 that uses ln_apr_obc
B) Initialize ln_apr_obc to .FALSE. where it is declared at the top of sbcapr.F90
