Segfault in tpch generator in tests

[lll-phill-lll]

How to reproduce:

cd ydb/tests/functional/tpc/medium
ya make -tt -F "test_tpch.py::TestTpchS1::test_tpch[1]"

Make sure that ulimit -c is not 0.

Reproduces only in debug built. So, this command finishes without any errors:

ya make -tt -r -F "test_tpch.py::TestTpchS1::test_tpch[1]"
