..and, by the way, this was documented: http://www.quantum-espresso.org/wiki/index.php/Installation#Linux_PCs_with_Pathscale_compiler
"Versions 2.3 ad 2.4 of the Pathscale compiler crash when compiling CPV/phasefactors.f90. Workaround: replace SUM(na(1:nsp)) with nat (info by Paolo Cazzato; fixed since version 3.1.1). Version 2.99 of the Pathscale compiler works and is recognized by configure for versions later than 4.0.1, but the preprocessing step: pathcc -E causes a mysterious error in compilation of iotk and should be replaced by /lib/cpp -P --traditional The MVAPICH parallel environment with Pathscale compilers also works. (info by Paolo Giannozzi, July 2008)" [note the "--traditional" instead of "-traditional" as I incoprrectly wrote in the preceding message] P. -- Paolo Giannozzi, Democritos and University of Udine, Italy
