Disassembler 'libcrypto-41.dll' - LibreSSL x64 2.5.1 - compile by Libre
developer itself using gnuc compiler ( version 5.4.0? ):
xor          ecx,ecx /* same as above! */
xor          r8d,r8d /* same as above! */
xor          edx,edx /* same as above! */
call         CreateMutexA /* CreateMutex(NULL, FALSE, NULL) */
mov          rcx,rax
mov          rax,rbx /* Different? */
lock cmpxchg [],rcx
test         rax,rax
jz          .
call         CloseHandle

Event 5.x got this problem too.
