[petsc-dev] Invalid read in PetscSubcommSetTypeGeneral

[Stefano Zampini]

Hong,

currently in master there's an error in PetscSubcommSetTypeGeneral, namely
in the loop starting at line 188

for (i=0; i<2*size; i++) {    subsize[recvbuf[i]] = recvbuf[i+1];}

recvbuf is allocated at line 178 as 2*size*sizeof(PetscMPIInt), and the
loop tries to read at location 2*size

Could you please fix it?
