Hi,
cryptsetup testsuite easily triggers following crash. I can provide more
info on demand, but currently most straightforward way to trigger it is:
1) checkout cryptsetup master branch
(https://gitlab.com/cryptsetup/cryptsetup.git)
2)./autogen.sh --disable-python --enable-integritysetup
3) compile
4) run tests/integrity-compat-test in loop for a while (it's not 100%
reproducible)
