If Gregor's answer does not solve it try adding -std=legacy to gfortrans compiler flags.

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,
