Test results are causing errors

[amanusk]

Description:
Running the tests seems to cause occasional errors. Some times the tests pass succesfully (as in the first example) and sometimes end with various errors, which seem related to PARI memory management.

System: Ubuntu 16.04
How to reproduce: cargo test --lib

Each run result is separated by -------------------------------------

test primitives::tests::test_encryption ... ok

test result: ok. 116 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out

----------------------------------------------------------


test tests::test_qf_to_pari_qf_to_qf ... ok
  ***   non-existent component: index > 13846213593583687105  ***   Error in the PARI system. End of program.
error: test failed, to rerun pass '--lib'

Update:
Ran only library specific tests, without binding tests.
The problem seems to occur since rust runs tests in parallel.
Examples:

> cargo test tests::
    Finished dev [unoptimized + debuginfo] target(s) in 0.16s
     Running target/debug/deps/class_group-aae55a43ccd626bf



running 5 tests

test primitives::tests::test_encryption ... ok

test result: ok. 5 passed; 0 failed; 0 ignored; 0 measured; 111 filtered out
