Using
gfortran -c -fopenmp --param=ggc-min-heapsize=0 --param=ggc-min-expand=0
bug.f90
the testcase reduces to
subroutine factorize_slu_r ()
factor_loop : do
!$OMP PARALLEL DO SCHEDULE (DYNAMIC) PRIVATE (info)
reduce_loop : do k = 1, n-l, 2*l
if(.NOT. (info >= 0)) then
stop
endif
end do reduce_loop
end do factor_loop
end subroutine factorize_slu_r
bug.f90: In function ‘factorize_slu_r’:
bug.f90:10:0: internal compiler error: Segmentation fault
end subroutine factorize_slu_r
