Dear developer,

I am using a machine whose architecture is not Intel.
The preconditioner 'gamg' fails in the setup phase, but there is no error information output. 
I guess maybe some variables  in gamg are not initialized when they are claimed,  specially those related to memory allocation.
The complier on this machine may not automatically initialize these variables to be zero? by default.
However, on other machines based on Intel, it works.

Can you please check the 'gamg' on this issue?
Thank you.
