Hello,

I'm currently trying to use my zymkey hsm with the azure sdk.

I follow the new tutorial (https://github.com/Azure/azure-iot-sdk-c/blob/secure_hsm_tutorial/provisioning_client/devdoc/secure_custom_hsm.md), so I checked out the hsm_secure branch.

I posted the issue here, because my problem is probably in this shared git, sorry if it is not the good place :)

Everything compile, but when i launch the command in order to run it (./provisioning_client/samples/prov_dev_client_ll_sample/prov_dev_client_ll_sample), it stops at the ENGINE_init(e)call, printing only Stack frame dump (0): and nothing else happens (but the program still run...)

I have 2 warnings when i compile:

/usr/bin/ld: warning: libssl.so.1.0.2, needed by /usr/lib/gcc/arm-linux-gnueabihf/6/../../../arm-linux-gnueabihf/libcurl.so, may conflict with libssl.so.1.1
/usr/bin/ld: warning: libcrypto.so.1.0.2, needed by /usr/lib/gcc/arm-linux-gnueabihf/6/../../../arm-linux-gnueabihf/libcurl.so, may conflict with libcrypto.so.1.1

The line where the code stops (i used gdb for that:)
https://github.com/Azure/azure-c-shared-utility/blob/hsm_secure/adapters/tlsio_openssl_secure.c#L1078

(gdb) next
1079	        if (ENGINE_init(e) != 1)
(gdb) next
Stack frame dump (0):
[New Thread 0x7680e430 (LWP 6683)]

(then i can't interact with gdb anymore, the program runs infinitly.)

Anyway, thanks for your work about the zymkey :)

[edit:]
After my last next, it consumes 100% of CPU, and when i kill the process in gdb, it says:

^C
Thread 1 "prov_dev_client" received signal SIGINT, Interrupt.
0x76d5f464 in pthread_join (threadid=<optimized out>, thread_return=0x0) at pthread_join.c:90
90	pthread_join.c: No such file or directory.

[edit2:]
the second thread is libzk_app_utils.so, perhaps the problem is in there side, so i asked this question in there forum too :)
