[mpich-discuss] _get_addr error while running application using MPICH

[Zhou, Hui]

Hi Zhifeng,

We just had a new mpich release: mpich-3.3rc1. You may try that 
release see if you still have the same error. 

That aside, does your code uses MPI_T_ interfaces? You may try search 
MPI_T_ prefixes in your code base. In particular, I am interested in 
any MPI_T_ calls before MPI_Init call.
