Hi. I encounterd the classical error severe (174): SIGSEGV, segmentation fault occurred when i call the lapack subroutine GESDD on my fortran (90) program with the ifort composer 2013 Linux.
!! Decomposition en valeurs singulieres
M = Factor_long*taille; N = 2*N_Emetteurs_CBFM
Allocate( AA(M,N), S(MIN(M,N)),U(M,M),VT(N,N), WW(MIN(M,N)-1))
AA = Epatch; call GESDD(AA,S,U=U, VT=VT, JOBZ='A')
Results on :
forrtl: severe (174): SIGSEGV, segmentation fault occurred
The real problem is that the error doesn't appear in the first passage through these code lines. it doesn't make any problem until a presize moment.
I have tried many things to rectify it : the option -heap-arrays; ulimit -s unlimited to increase my stack size .... it doesn't work.
I don't know if this can be rectified if I use the fortran Interface !?
Can I have some help if possible Pleaaaaaaaaaaaaaase !
