HandleManager 'No such file or directory', segmentation fault

[NickDarvey]

I'm trying to use SoftHSMv2 in OpenSSL via pkcs11-provider. I'm building SoftHSMv2 from source, a181dae. When I try to sign something I get a seg fault.

root@d9a3a7531a3c:/# echo "test" > test.txt
   openssl pkeyutl -provider softhsm -sign -inkey "pkcs11:object=test;type=private" -in test.txt -out signature.bin
Enter pass phrase for PKCS#11 Token (Slot 479520929 - SoftHSM slot ID 0x1c94e8a1):
Segmentation fault (core dumped)

Running it under gdb, It looks like it's this line that is failing. (gdb output below.)

SoftHSMv2/src/lib/handle_mgr/HandleManager.cpp

Line 75 in a181dae

MutexLocker lock(handlesMutex);

This may be related, #635 (comment).
