Package: libgmp10

Severity: serious
Justification: Policy 7.3

Dear Maintainer,

After a routine `apt-get update; apt-get dist-upgrade`, several packages are 'kept back', including 'libgmp10'.  

Please see #1125764 regarding libasyncns0 -- this is the exact same situation, only the names and version numbers are changed.

TLDR: package has :amd64 and :i386 arch builds; the :amd64 package states that it 'Breaks:' the i386 package of different versions.  But the NMU uploaded only :amd64, so that package cannot be updated on systems with both arch packages installed.

Again, see #1125764 for more details.
