CST HSM - Segmentation fault (core dumped)

Hello,

I have implemented solution to sign the u-boot and zImage with CST tool. Now I would like to implement CST tool to work with HSM module. I already have PKI tree generated on the HSM. I created the CST tool with back_end-hsm, create hsm.cfg file with path to the certificate and run CST tool. After a moment I get error Segmentation fault (core dumped). With cst tool located in /linux64/bin/cst there is no problem to sign the image, but with back_end-hsm I get segmentation fault. (CST 3.1.0 and also with CST 3.2.0)

EDIT:

I am using module libsc-hsm-pkcs11.so, error is on the line 589 (ENGINE_ctrl_cmd_string (eng, "MODULE_PATH", hsm_conf.module_path, 0);)

Thank you for any idea.

Best regards

Tomas Klein
