Hi all,
With the current master (182e974) I get a weird segmentation fault for
*float* numbers when calling
a = make_vectorized_array<value_type>(0.);
inside a constructor of my class where
VectorizedArray<value_type> a;
I see this only on a cluster (Intel Xeon Ivy Bridge), deal.II is compiled
with *-march=native* with GCC 4.8.5 in Debug mode (obviously segmentation
fault is there in Release as well).
Unfortunately, I wiped the old (working) installation and can't check it
now,
but I think this used to work with *-march=native* a few months back.
Relevant config tests are:
-- Performing Test DEAL_II_HAVE_SSE2
-- Performing Test DEAL_II_HAVE_SSE2 - Success
-- Performing Test DEAL_II_HAVE_AVX
-- Performing Test DEAL_II_HAVE_AVX - Success
-- Performing Test DEAL_II_HAVE_AVX512
-- Performing Test DEAL_II_HAVE_AVX512 - Failed
-- Performing Test DEAL_II_HAVE_OPENMP_SIMD
-- Performing Test DEAL_II_HAVE_OPENMP_SIMD - Failed
If I try to replicate what *make_vectorized_array* does, then it works fine
whereas calling it gives segfault:
const value_type u = 0.;
VectorizedArray<value_type> result;
result = u;
// ^^ copy paste of make_vectorized_array
a = u;
VectorizedArray<double> dummy = make_vectorized_array<double>(0.); //
<- quick test for doubles
a = make_vectorized_array<value_type>(0.); <===== Segmentation
fault here!
I am puzzled with this... Any ideas where to dig?
Cheers,
Denis
