no such vector element

no such vector element

[Mathew Yeates]

I am getting this error when I try and access a fortran array.

>p Opt_depth_ref_per_band(2,2)
no such vector element

Opt_depth_ref_per_band is an array with 4 rows and 74 columns.

It is declared as
real,    intent(out), dimension(NBAND, Num_mixture) :: &
      	   Opt_depth_ref_per_band

Where NBAND is a constant and Num_mixture is an argument to the subroutine.

I can print values by using x/f on the array address.

Any ideas?

Offhand this sounds like the known VLA problem.

I know Jan has a branch for this in the archer repository, but I don't
know the current status.

The branch gets updated only for each Fedora release which roughly corresponds
to FSF GDB releases.

Maintaining existing testcases as PASSing.

There exist various new failures of that branch such as
	http://sourceware.org/bugzilla/show_bug.cgi?id=9395#c4
and others

but currently planning to merge it first to FSF GDB before fixing them as this
kind of extension is difficult to maintain off-trunk.
