[Q-e-developers] ifort 12.1.0 segfaults in fft_parallel.f90

[Filippo Spiga]

Thanks Lorenzo. This is the closest version to yours I have installed on my HPC system:

$ ifort --version
ifort (IFORT) 12.1.0 20111011
Copyright (C) 1985-2011 Intel Corporation.  All rights reserved.

It does not show the problem. I googled differences between 20111011 (Intel 12 Update 7) and 20110811 (Intel 12 Update 6) but Intel does not publish proper ChangeLog of compiler bug fixes.  Intel 12 Update 5 should be reported as 12.0 by "--version". Anyway, those are details. The problem is really on that specific Intel compiler build you have and it has been disappeared ever since.

I noticed Paolo committed a fix. If possible my suggestion is to upgrade Intel 12 to something more modern e.g. Intel 14.
