engine: test_tls hangs and test_engine fails with OpenSSL-3.0 master

MacOS 10.15.4, Xcode-10.15.4, current master of OpenSSL, current master of this engine.

Build succeeds. All tests for OpenSSL-1.1.1 pass, test_tls takes less than 4 seconds.

Tests for OpenSSL-3.0 hang on the test_tls:

Running tests...

And you probably want to see this:

      Start  5: TLS

5: Test timeout computed to be: 10000000

5: /Users/ur20980/src/grasshopper-engine/test_tls.c:76: OpenSSL internal error: SSL_CTX_use_certificate(ctx, cert)
5: Test rsa

Also, please feel free to guide me how to try other tests (6-10).

Update

First, it seems that the majority of the other tests are OK.

It appears that the reason for the test_tls to fail is this strange line, and commenting it out is a workaround:

diff --git a/test_tls.c b/test_tls.c

     ret |= test("gost2012_256", "B");
     ret |= test("gost2012_256", "C");

It appears that the (unnecessary in my humble opinion) name conversion from “Grasshopper” to “Kuznyechik” (amazing spelling, BTW) was incomplete, causing the engine test to fail:
