[Wrf-users] Stack trace terminated abnormally

[Alex Fierro]

Greetings:

If you are running on a Mac, use those flags at linking stage only to
increase the stack (As setting the stacksize to unlimited in your bashrc
etc does not suffice):

-stack_addr,0xF10000000 -Wl,-stack_size,0x64000000

However, from what I see below your run stopped due to a Seg Fault error:
either there is a bug in your code or your time step size is too large (CFL
criterion exceeded).

Cheers and hope this helps,

Alex-
