<div class="moz-cite-prefix">Dear Bramha,<br>
as Andrea Dal Corso already pointed out, this may be due to
incompatibilities with the linking to the blas libraries. It
appears that you are using your system-provided blas and lapack
libraries.<br>
<br>
As Andrea said, try to reconfigure quantum espresso adding the <br>
<meta http-equiv="CONTENT-TYPE" content="text/html;
charset=ISO-8859-1">
<title></title>
<meta name="GENERATOR" content="LibreOffice 3.5 (Linux)">
<style type="text/css">
<!--
@page { margin: 0.79in }
P { margin-bottom: 0.08in }
-->
</style>--with-internal-blas --with-internal-lapack<br>
flags to the ./configure and then recompile everything to see if
the problem disappears. <br>
<br>
In fact, there is a known incompatibility problem between the
calling convention for functions that return complex values: one
is the one used by g77/f2c, where in practice the compiler
converts such functions to subroutines with a further parameter
for the return value; gfortran instead produces a normal function
returning a value (and maybe also ifort?). If your system
libraries were compiled using g77, and you instead use gfortran
(or possibly ifort?) your code may crash or produce random
results. This typically happens with zdotc, which is one the most
commonly used complex-returning functions in blas+lapack.<br>
<br>
For further details see for instance this link:<br>
<a class="moz-txt-link-freetext" href="http://www.macresearch.org/lapackblas-fortran-106#comment-17071">http://www.macresearch.org/lapackblas-fortran-106#comment-17071</a><br>
<br>
Otherwise, another trick that you can try if you use gfortran and
you confirm that this is the problem, is to add the -ff2c flag to
all compilations with gfortran. But the best probably is to use
libraries compiled with the same compiler, or at least libraries
that are verified to work with your compiler (in your case, since
it appears that you use ifort, you may want to link to the proper
intel MKL libraries).<br>
<br>
Best,<br>

Please provide your make.sys, or try to link with the internal
blas and<br>
lapack libraries. I do not know if this apply to your case,
but I have<br>
seen an error similar to the one that you report due to a
problem with<br>
the blas library. find_mode_sym is just the first routine that
uses<br>
zdotc.<br>
