Greetings from Guix! [0]
We're having trouble building ilmbase-2.2.0 for the i686 architecture on
Linux, with gcc-4.9.3.
The build process fails during testing. Specifically, it fails
testBoxAlgo, like this:
ImathTest: testBoxAlgo.cpp:892: void {anonymous}::boxMatrixTransform():
Assertion `b21 == b2' failed.
/gnu/store/isxqjfaglyfsbcv75y8qbqbph8v28ykr-bash-4.3.39/bin/bash: line 5: 4565
Aborted ${dir}$tst
On our mailing list, this was suggested as the nature of the problem

Here is the build system's web page for this particular build...
http://hydra.gnu.org/build/729299
... and the full build log...
http://hydra.gnu.org/build/729299/nixlog/1
... and an exhaustive list of build dependencies (be patient, it
may take a few seconds to load)...
http://hydra.gnu.org/build/729299#tabs-build-deps
We have no problem building on x86_64, armv7, or mips64el.
Thanks for reading,
Leo
