Sorry for spamming, but I forgot to mention that I also tried
running the test with an executable generated with debug flags (-CB)
and no apparent problems with arrays or allocations emerge. <br>

make things more reproducible, I rerun some tests with clean

the gamma only algorithm, you can find the input and outputs
attached. There are some small differences in the numbers, but the
overall effect is the same, the SCF goes nuts. I would like to
stress that the problem is not system specific, the same happens
for the input atomic positions translated or in larger cells, with
or without martyna-tuckerman correction, and the same happens for
many anions (10 out of 60, including OH-), even though all these
tests were performed with a local version of QE. As I said briefly
in the previous email, the local modifications do nothing for this
specific calculations, i.e. anions in vacuum, and actually when
you include a dielectric medium the calculations do converge. I
understand that it is always better to be extremely careful with
local modifications, but after the tests of today I would be even
more confident that the problem is in QE, not in our version.
