The assertion-failure in comment 0 is: `Inconsistency detected by ld.so: ../elf/dl-tls.c: 481: _dl_allocate_tls_init: Assertion `listp->slotinfo[cnt].gen <= GL(dl_tls_generation)' failed!` which is bug 1819763. There are details in that bug, but tl;dr this is a bug in glibc specifically on old versions of Ubuntu (note that the test-run linked in comment 0 here is from Ubuntu 18.04). My understanding is that we're stuck with this randomly happening until we get rid of these Ubuntu 18.04 test runners. In the meantime, we can ignore this assertion and dupe bugs to bug 1819763 as I'm doing here. If there's a particular test that reliably triggers it (outside of test-verify mode), it might be worth considering flagging that test as skipped on Ubuntu 18.04 I suppose.
