Bug#1017468: openfst: FTBFS in dh_auto_test due to excessive memory usage

[Nick Rosbrook]

Package: openfst
Severity: serious
Tags: patch ftbfs
Justification: fails to build from source (but built successfully in the past)
User: ubuntu-devel at lists.ubuntu.com
Usertags: origin-ubuntu kinetic ubuntu-patch

Dear Maintainer,

The openfst build was failing both locally and on Ubuntu build
infrastructure[1] during dh_auto_test. In both situations, the build
process was getting killed due to excessive memory usage. In Ubuntu, the
attached patch was applied to reduce the memory usage during
dh_auto_test.

  * debian/rules: Set --max-parallel=2 in override_dh_auto_test to avoid
    excessive memory usage resulting in FTBFS (LP: #1984137).

Thanks,
Nick
