ifort: everithing ok, but with gfortran: segmentation fault

When I use the mozart chemistry mechanism (chem_opt = 202) and run real.exe with a wrf compiled with gfortran, I get error "Program received signal SIGSEGV: Segmentation fault - invalid memory reference." , but the same input file and namelist work fine in wrf compiled by intel compiler.
Is there a solution to this？I compiled with 100 cores and have 512g of RAM, tried 'ulimit -s unlimited' but it didn't work!

are you able to figure out this problem
 
No issue, I have resolved the problem you have to run real.exe without chemistry. And then mozbc to add boundary condition and then switch on your chemistry and run wrf.exe
