Problems using CGEQRF

holysword — Sun, 16 Sep 2012 18:27:13 GMT

I am trying to use Lapack's cgeqrf routine but there is something wrong:

!---------------------------------------------------------------

program main

implicit none

integer,parameter :: p = 5
complex :: tau(p), u(p,p), work(p)

u = cmplx(1.0,0.0)
tau = cmplx(0.0,0.0)
work = cmplx(0.0,0.0)

call cgeqrf(p, p, u, p, tau, work, p)

end program main

!---------------------------------------------------------------

Then, when trying to run:

† perjanus † Area51 $ ifort -L/opt/intel/composerxe/mkl/lib/intel64/ -traceback -mkl ./main.f90 -o main.exe
† perjanus † Area51 $ ./main.exe
forrtl: severe (174): SIGSEGV, segmentation fault occurred
Image PC Routine Line Source
libmkl_intel_lp64 00007F92E6F46A64 Unknown Unknown Unknown
main.exe 0000000000403880 MAIN__ 13 main.f90
main.exe 000000000040371C Unknown Unknown Unknown
libc.so.6 00007F92E3F334BD Unknown Unknown Unknown
main.exe 0000000000403619 Unknown Unknown Unknown
† perjanus † Area51 $

Am I doing something wrong? I am using ifort 12.1.5 20120612 (don't know how to find mkl version, but it came in the same bundle with ifort and icc).

Thanks in advance
