allocate source bug , memory corruption

[pat97269]

Hi,I report a bug on allocate with the source statement. When doing multiple allocate./deallocate in a loop, it ends with segfault on the spread intrisic function. The solution is actually to separate the allocate and the assignement, which point the source statement. ifort v12.1Pat
[fortran]program test implicit none double precision,dimension(:,:),allocatable :: bestmatrix,rand_mat,popul double precision,dimension(:),allocatable :: bestmem integer :: i,np=500,j logical,dimension(:),allocatable :: mask integer,dimension(:),allocatable :: indd allocate(bestmem(np),bestmatrix(np,100),rand_mat(np,100),popul(np,100)) allocate(mask(np)) call random_number(bestmem) call random_number(popul) call random_number(rand_mat) do i=1,10000000 call random_number(bestmem) mask=bestmem
