Hmm, I think I fixed it. Aitor, Sabrina, would it be possible to try trunk (32769+)? If this works for you, then I will include it in the next release (0.3.1) as soon as you reply back.

Aitor, Sabrina,
I'll try to fix this today. Your platforms are standard 32bit right?
Cheers,
Radu.

Hi Sabrina,
adding -DEIGEN_DONT_VECTORIZE didnt work for me either. Then I found
this document:
http://eigen.tuxfamily.org/index.php?title=FAQ#I_disabled_vectorization.2C_but_I.27m_still_getting_annoyed_about_alignment_issues.21
Define EIGEN_DONT_ALIGN
Or define both EIGEN_DONT_VECTORIZE and
EIGEN_DISABLE_UNALIGNED_ARRAY_ASSERT
Tried all possible combinations but it didnt work :) I was still
becoming the assertion. So, what I did in the end (not a very clean
solution) was,
Added this to CMakeList.txt in pcl:
add_definitions(-DEIGEN_DISABLE_UNALIGNED_ARRAY_ASSERT
-DEIGEN_DONT_VECTORIZE)
add_definitions(-DEIGEN_DONT_ALIGN)
and finally comment the line in MapBase.h giving the assertion.
//ei_assert(EIGEN_IMPLIES(ei_traits<Derived>::Flags&AlignedBit,
(size_t(m_data)&0xf)==0)
// && "data is not aligned");
and remake PCL...
No idea which side effects this might have but its working fine now.
Anyway, just a temporal dirty solution.
Hope it works for you too.
Regards
Aitor

Hi Radu,
I am facing a similar problem as Aitor (I am using the
tabletop_object_detector). Which CMakeLists.txt do I have to
modify
exactly?
I tried the CMakeLists.txt in pcl then "make clean" and
"make", but
still get
the failed assertion.
Regards,
Sabrina
