Some of the configure options changed their name for the 1.3. Here is
the updated list you should use in order to get valgrind support for

george.
For some reason that still doesn't work for me. I tried both
flag "--with-memory-manager=none" and "--without-memory-manager" and
it
didn't seem to make any difference.
Attached is my config.log generated by configure script.
Here's what I get, when compiling with mpif90

This is different than if I just use gfortran:

$ valgrind --leak-check=full ./a.out

Here's the very simple test code:
$ cat testMemchek.f90
program testMemcheck
real, dimension(:), pointer :: &
mypointer
real, dimension(3), target :: &
mytarget
mytarget = 2.345
allocate(mypointer(10))
mypointer = .5567
print*, mypointer(2)
mypointer => mytarget
end program testMemcheck
Am I missing something ? Thanks.

What
