segfault when using heevr from lapack95

[jakub_z_]

'm trying to use the heevr routine from lapack95 in fortran, but I'm getting segfault. I'm using the parallel studio xe 2016 composer edition for fortran update3. Here is a sample code, which shows the problem:

program test
use lapack95
implicit none

integer, parameter:: dp=kind(0.d0)

complex(dp), allocatable :: A(:,:)
real(dp), allocatable :: w(:)
integer :: n

n=20
allocate(A(n,n))
allocate(w(n))
A(:,:) = 0_dp

call heevr(A,w)

end program

I use the following command to compile: 

ifort test.f90 -heap-arrays  -check all -warn all -g -traceback -I${MKLROOT}/include/intel64/lp64 -I${MKLROOT}/include  ${MKLROOT}/lib/intel64/libmkl_lapack95_lp64.a -Wl,--start-group ${MKLROOT}/lib/intel64/libmkl_intel_lp64.a ${MKLROOT}/lib/intel64/libmkl_core.a ${MKLROOT}/lib/intel64/libmkl_sequential.a -Wl,--end-group -lpthread -lm -ldl -o test.x

It complies fine, but when I run it a segmentation fault occurs:

forrtl: severe (174): SIGSEGV, segmentation fault occurred
Image              PC                Routine            Line        Source

libpthread.so.0    00007FC2936BA3D0  Unknown               Unknown  Unknown

The segmentation fault does not occur if n<11 or if I use heevd instead of heevr. The stack size is set to unlimited.
