Hi,
when compiling and linking the following program:
% cat openmp-test.F90
implicit none
#if _OPENMP >= 200505
!$ integer :: OMP_GET_NUM_THREADS, OMP_GET_MAX_THREADS, OMP_GET_THREAD_NUM
#else
integer :: OMP_GET_NUM_THREADS, OMP_GET_MAX_THREADS, OMP_GET_THREAD_NUM
#endif
integer :: i
print *, "OpenMP version:", _OPENMP
print *
!$OMP parallel do
do i = 1, OMP_GET_MAX_THREADS ()
print *, "OMP_GET_THREAD_NUM
=",OMP_GET_THREAD_NUM(),OMP_GET_NUM_THREADS()
end do
!$OMP end parallel do
end program
% gfc4x -O -g -fopenmp openmp-test.F90 -fwhopr
lto1: error: missing callgraph edge for call stmt:
# .MEM_26 = VDEF <.MEM_25>
_gfortran_st_write (&dt_parm.2);
lto1: error: missing callgraph edge for call stmt:

1}, 20);

[...more output...]
lto1: internal compiler error: verify_cgraph_node failed
and similar for -flto.
The error disappears when either -O, -g, -fwhopr or -flto are
removed.
Cheers,
