WRFDA 4dvar segmentation fault in tutorial

Hello, I have been working through the WRFDA tutorial (https://www2.mmm.ucar.edu/wrf/users/wrf ... 4dvar.html). All the examples I tried went fine until trying to run the 4dvar case, at which point I just get a mysterious segmentation fault:

"Program received signal SIGSEGV: Segmentation fault - invalid memory reference."

I attached the relevant error and log files.

Thanks!

Sofia

Hello,

Were you able to solve this? I have a similar issue on the example tutorial in the documentation. I encountered CFL errors and tried to:
a) reduce the time step
b) use damping
c) use smooth_cg_topog
d) use epssm

but non of the above solved the issue. Please let me know if you were able to figure this out!
