[mpich-discuss] mpich2.1.4.1p1: intercomm_create.c

In src/mpi/comm/intercomm_create.c from lines 58, the calculation of maxi seems to be incorrect when maxlpid is a multiple of 32. /* Compute the max index and zero the pids array */ maxi = (maxlpid + 31) / 32; if (maxi >= MAX_LPID32_ARRAY) { MPIU_CHKLMEM_MALLOC(lpidmask,int32_t*,maxi*sizeof(int32_t), mpi_errno,"lpidmask"); } else { lpidmask = lpidmaskPrealloc; } for (i=0; i<maxi; i++) lpidmask[i] = 0;
