A description of the bug behavior
I am using MASA via the Fortran90 interface and compiling my source code with the following Intel Fortran compiler:
mpif90 for the Intel(R) MPI Library 2018 Update 3 for Linux*
Copyright(C) 2003-2018, Intel Corporation. All rights reserved.
__INTEL_PRE_FFLAGS options: -gcc-name=core-gcc -gxx-name=core-g++
ifort version 18.0.3
When I use the following flags (among others) to compile my source code, specifically
-check all,noarg_temp_created -init=snan -init=zero -init=arrays
I obtain the following runtime error when running my executable:
forrtl: error (73): floating divide by zero

For reference, Line 10911 in my Fortran90 source code is a call to masa_init:
!-- initialize the problem
call masa_init('test',trim(adjustl(desired_mms_function)))
where desired_mms_function = 'euler_2d'. Note that when I compile without the aforementioned flags (i.e., without -check all,noarg_temp_created -init=snan -init=zero -init=arrays), MASA runs correctly. For reference, the functions of the flags of interest are as follows (more info here):
-init=arrays specifies that we initialize all unitialized arrays and variables by the following;
-init=nan initializes all unitialized REAL and COMPLEX variables/arrays to nans to get caught by the nantrapping
-init=zero initializes all unitialized REAL, COMPLEX, INTEGER, and LOGICAL variables/arrays to zero
My guess is that there are some unintialized variables in MASA, potentially in fans_sa.cpp (based on the above error message that I am getting), that are being caught by these flags, however I have been unable to identify specifically what part of the code is leading to the runtime error. Does anyone know how to address this issue?
