Package: libc6-i686 Version: 2.19-18+deb8u1 Severity: important Hi,
I was trying to create a local backport of python-cffi onto jessie/i386. On a system with libc6-i686 installed, I get a failure in the self test of the build: > assert library.sin(12.3) == math.sin(12.3) E assert 0.8444952930965295 == -0.26323179136580094 Uninstalling libc6-i686 lets the full build and tests run through. Something very related has already happened before: https://www.sourceware.org/bugzilla/show_bug.cgi?id=16625 This suggests a compiler bug in gcc 4.8. But jessie is compiled with 4.9, so it must be something a bit different. Severity: important as giving wrong results to math functions isn't something trivial, really and can affect multiple unrelated components/packages. Cheers Christian -- www.cosmokey.com
