sm2_do_decrypt error on OpenResty ARM64 machine.

Error

/root/GmSSL-3.1.1/src/sm2_lib.c:683:sm2_do_decrypt():

Descryption

I wrote a lua encapsulation based on the GMSSSL library and uses FFI to load the GMSSSL library to implement GM functionality. This lua code which I wrote in a Windows environment and runs correctly on Windows。
the test.lua run correct when i tried run the lua encapsulation on arm64 machine command line: luajit test.lua.
but sm2_do_decrypt got error when i require the encapsulation in ngx.lua code and use it.

my lua encapsulation

lua-gmssl
