Unable to reload C module

I have trouble with reload c module in Tarantool
I have a C module which expose a method:
int calculate(lua_State* L);

in addition i declared entry point:

extern "C"
{    
    LUA_API int luaopen_cuendemodule(lua_State *L);
}

now, i load this module ("testmodule.so") in tarantool:

require('testmodule')
box.schema.func.create('testmodule.calculate')
box.schema.user.grant('user', 'execute', 'function', 'testmodule.calculate')

and now I call this method from my C# client:
await tarantoolClient.Call<TarantoolTuple<CalculateParameters>, CalculationResults>("testmodule.calculate", TarantoolTuple.Create(....));
and it is work as expected - method calculate executed and results was returned

but if I want update my module than the problems begin: after I replace so file and call calculate method my Tarantool restart and I can see something like "Tarntool invalid opcode in testmodule.so" in dmesg

after reading documentation i see additional parameters in function definition like this:
box.schema.func.create('testmodule.calculate', {language = 'C'})
but after this if i call it from C# i receive exception with message "failed to dynamically load function undefined symbol calculate"

Version of Tarantool - 1.7
Version of GCC - 8.1.0

Start with the C entry point luaopen_cuendemodule and the box.schema.func.create calls shown in the report, then reproduce replacing testmodule.so on Tarantool 1.7. Compare the normal registration with the {language = 'C'} path and verify that reloading the module no longer causes an invalid opcode or an undefined symbol error.
