Extended Description

Precondition:

1. LLVM 9.0.0 builded by MSVC 2019 in Debug build variant.
2. Builded application: OrcJIT example from llvm-9.0.0.src/examples/HowToUseLLJIT/HowToUseLLJIT.cpp (linked with LLVM build from step (1)).

Steps to reproduce:

1. Run application.

Expected result:
The application should work fine.

Actual result:
The application failed on an assertion in OrcJIT core (Core.cpp:384):

Assertion failed: I->second == KV.second.getFlags() && "Resolving symbol with incorrect flags", file C:\Workspace\llvm-9.0.0.src\lib\ExecutionEngine\Orc\Core.cpp, line 384
