This issue is due to my broken logic in debian/rules:

# Set number of parallel workers for tests
ifneq (,$(filter parallel=%,$(DEB_BUILD_OPTIONS)))
TESTS_ENV += JULIA_CPU_CORES=$(patsubst parallel=%,%,$(filter parallel=%,$(DEB_BUILD_OPTIONS)))
else ifeq (,$(filter parallel,$(DEB_BUILD_OPTIONS)))
TESTS_ENV += JULIA_CPU_CORES=2
endif
# Restart workers exceeding maximum resident memory size (requires JULIA_CPU_CORES >= 2)
TESTS_ENV += JULIA_TEST_MAXRSS_MB=500

I assumed that the number of processes is ≥ 2 for parallel builds, but
this is no longer the case since debhelper 10 always passes "parallel".
I will upload a new version soon that ensures JULIA_CPU_CORES ≥ 2.

By the way, Graham, can we increase debhelper compat level to 10?
