[issue45797] AMD64 Arch Linux Asan Debug buildbot sometimes hangs before tests complete

[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

Example:

AMD64 Arch Linux Asan Debug 3.10:
https://buildbot.python.org/all/#/builders/621/builds/351

(...)
1:13:40 load avg: 1.85 [420/421/1] test_reprlib passed
1:13:41 load avg: 1.85 [421/421/1] test_funcattrs passed
command timed out: 1200 seconds without output running [b'make', b'buildbottest', b'TESTOPTS=-j1 -x test_ctypes test_capi test_crypt test_decimal test_faulthandler test_interpreters --junit-xml test-results.xml ${BUILDBOT_TESTOPTS}', b'TESTPYTHONOPTS=', b'TESTTIMEOUT=900'], attempting to kill
make: *** [Makefile:1255: buildbottest] Terminated
process killed by signal 15
program finished with exit code -1
elapsedTime=5623.934168


Can it be related to bpo-45200 "Address Sanitizer: libasan dead lock in pthread_create() (test_multiprocessing_fork.test_get() hangs)"?
