Hi: I've been experimenting building our modestly large FORTRAN program with OpenF95 126.96.36.199. When I build with OpenMP and -O3, I get a segmentation fault in a parallelized loop. The parallelized loop is relatively straight-forward, but it is nested and it references an array element of an array of user-defined types, which itself contains an array. Also, there is yet another interior implicit loop over the leading dimension of these arrays.
do i = 1, n
do j = i, m
!$omp parallel do
do k = 1, o
do l = 1, p
A(:,l,k) = A(:,l,k) + B(:,l,k) * C(j)%D(:,l,k)
!$omp end parallel do
I abstracted this bit of code into a separate program and compiled it, but I cannot reproduce the segmentation fault. Could you give me some suggestions on how to reduce my code to something which I can post?
