[QE-users] GIPAW Segmentation Fault

Dear Ben,
     I'm afraid it's a problem with MKL-blas ZDOTC, which must
return a complex(dp) result. Very strange, because if you grep
the source code, we have declared it: complex(dp), external::zdtoc

Can you tell us your compiler and MKL version? can you add
DFLAGS+=-Dzdotc=zdotc_wrapper
to the QE make.inc and recompile both (QE and GIPAW)?

Best wishes,
     Davide
