Potential regression in gfortran 4.3.3

[Harald Anlauf]

Hi,

using Tobias' snapshots for x64_64, I am seeing a potential regression
in gfortran 4.3.3 between revs. r142852 and r142864.  I am still working
to reduce the problem to a manageable size which might take some time,
so this is just a head-up.  Anyway, the problem appears to be related to
passing arrays which are sections of pointer components of derived types.
I am suddenly getting an array bounds violation from r142864, but not from
previous versions (nor from other compilers).

The code in question is a subroutine call:

    call tq_tvgh (var_f% av (k_lev:,1,1),  ...)

where checks on var_f% av are positive:

 associated: T
 shape     :          43           4           1
 lbound    :           1           1           1
 ubound    :          43           4           1

but I get:

At line 1167 of file ../../../../oo-model/mo_tovs.f90
Fortran runtime error: Array reference out of bounds for array 'var_f', lower bound of dimension 2 exceeded(1 < 9221120237041090560)

Mabe this rings a bell.
Mikael, any ideas whether your recent fix to PR38487 could be relevant here?

Anyway, I'll work on a reduced example.

Cheers,
Harald
