Hi,

Could you add the machine and Os spec on this item - thanks.

from openexr.

We are building in KVM (ppc970) and OS is openSUSE Factory (read almost equal to upcomming 12.2)
The same occurs with building it on PowerLinux 7R2 machine (Power7)

from openexr.

Thanks for the update. I can start taking a look week after next

from openexr.

Cool, let me know, If I can provide additional information here..

I'm seeing the same issue with 1.0.3 on Fedora when building natively on ARM using a PandaBoard.

I think we have it fixed. Both arm and PowerPC with following patch:

from openexr.

FWIW this issue seems to apply to all archs except for amd64 and i386. (Tested: s390, amr, mipsel, ia64, PowerPC)

from openexr.

Fixed in the internal repo, will be available in v2.2.
