[mpich-discuss] Error in MPI_IRECV

Hi,
let me guess: this code uses `include mpif.h` and is compiled with
gfortran. If so, try to add `-fallow-argument-mismatch' to your compiler
flags.
Explanation: With the include file, there are no explicit interfaces and
the compiler generates an implicit interface from the call to
`MPI_IRECV`. Having two calls with different argument types is an error
since some gcc version (10 IIRC).
Cheers,
Gregor Corbin
