I have encountered a similar problem when running test case of ima-evm-
utils with softhsm used as engine on Ubuntu 24.04 (Noble). In this case
I am also crashing in pkcs11_slot_unref when this line here is called:
CRYPTOKI_call(slot->ctx, C_CloseAllSessions(slot->id));
https://github.com/OpenSC/libp11/blob/libp11-0.4.12/src/p11_slot.c#L433
ima-evm-utils: https://github.com/mimizohar/ima-evm-utils-test/
The evmctl utility has left main() when the crash occurs. So this function is
called via some OpenSSL destructor code path. When OPENSSL_cleanup() is called
before main() exits then this crash does NOT occur.
When single stepping through the crash then it seems that C_CloseAllSessions()
does not get called anymore but the crash occurs when it seems like it was
trying to call this function.
0x00007ffff7fb3530 <+96>: call 0x7ffff7fae110 <OPENSSL_cleanse@plt>

0x00007ffff7fb354d <+125>: mov 0x70(%rbx),%rdi
0x00007ffff7fb3551 <+129>: mov (%rax),%rax
0x00007ffff7fb3554 <+132>: call *0x78(%rax) <----- crash
occurs here
0x00007ffff7fb3557 <+135>: mov 0x78(%rbx),%rdi
Notes:
- When SoftHSM is used in a test case via an OpenSSL provider, this same crash
does NOT occur.
- The same test passes on Fedora (latest) when using SoftHSM either via engine
or provider interfaces.
- Another problem is that I cannot use OPENSSL_cleanup before main() exit since
tests on AltLinux and Debian end up failing then for some unknown reason.
