When testing a possible patch for bug #669508 inside a 32bit chroot, I came across the following error:

     static_assert (sizeof(size_t) == sizeof(Partio::ParticleIndex),
     ^~~~~~~~~~~~~

When I checked the latest partio-1.5.4 sources, I found ParticleIndex to be declared like

//! Opaque random access method to a single particle. No number is implied or guaranteed.
typedef uint64_t ParticleIndex;

On 64bit machines this might evaluate to the same size as size_t, but not on 32bit arches. BTW in a 64bit clean chroot, osl compiled against partio-1.5.4.

I have two ideas on how this issue could be solved:
a) remove x86 arch from partio
b) mask partio USE flag on osl for x86 arches
Further ideas are appreciated!

The packages were emerged like
(chroot 32) artus / # emerge -pqv =media-libs/partio-1.5.4::gentoo
[ebuild   R   ] media-libs/partio-1.5.4  USE="-doc" PYTHON_SINGLE_TARGET="python3_6 -python2_7 -python3_4 -python3_5" PYTHON_TARGETS="python2_7 python3_6 -python3_4 -python3_5" 

and

(chroot 32) artus / # emerge -pqv =media-libs/osl-1.9.9::gentoo-git
[ebuild  N    ] media-libs/osl-1.9.9  USE="partio -doc -test" CPU_FLAGS_X86="-avx -avx2 -avx512f -f16c -sse2 -sse3 -sse4_1 -sse4_2 -ssse3"

Created attachment 558160 [details]

emerge --info from the 32bit chroot environment.
