[Wrf-users] Segmentation fault with ARWpost

[Dmitry N. Mikushin]

Hi Srikanth,

Debugger is unable to find the sources to point you to the location of
segmentation fault. If you are building and running the model on the same
machine (or sources should be available in some other way), I guess this is
happening because WRF uses temporary .f files as result of preprocessing
original .F sources, and deletes them afterwards. You might want to track
the part of compile script, which deletes them and disable it.
