This patch provides a workaround for two bugs affecting the compilation of qe_6.4 and newer versions. The patch has been verified to work for Intel compiler versions from 11.0 to 15.0.
These bugs are actually pretty different:
- The first bug affects versions from 11.0 to 13.0. The compilation terminates correctly but at runtime presents a segmentation fault analogous to the one reported in this issue [#106 (closed)].
- The second bug affects instead the compilation with ifort versions from 14.0 to to 15.0 with an internal compiler error.
