[...] If you get mysterious errors in the provided tests and  
examples: your compiler, or your mathematical
libraries, or MPI libraries, or a combination thereof, is very likely  
buggy. Although the presence of subtle
bugs in QUANTUM ESPRESSO that are not revealed during the testing  
phase can never be ruled out,
it is very unlikely that this happens on the provided tests and  
examples.

10.1.0.9 pw.x crashes with segmentation fault or similarly obscure  
messages
Possible reasons:

     * too much RAM memory or stack requested (see next item).
     * if you are using highly optimized mathematical libraries,  
verify that they are designed for your hardware.
     * If you are using aggressive optimization in compilation,  
verify that you are using the appropriate options for your machine
     * The executable was not properly compiled, or was compiled on a  
different and incompatible environment.
     * buggy compiler or libraries: this is the default explanation  
if you have problems with the provided tests and examples.
