Assertion `block->type.isConcrete() && singleton->type == Type::unreachable'

Hi,

we have created a experimental project with SDL2 and some other libs and want to build it with emscripten.
I am using cmake with the following emscripten specific options:

**CMake Options**
```
target_compile_options(sdlcpp PUBLIC
-fexceptions
)
target_link_options(
sdlcpp PUBLIC
-fexceptions
"-sASSERTIONS=1"
"-sALLOW_MEMORY_GROWTH=1"
"-sUSE_SDL=2"
"-sUSE_SDL_IMAGE=2"
"-sUSE_SDL_MIXER=2"
"-sUSE_SDL_TTF=2"
"-sSDL2_IMAGE_FORMATS=['bmp','png','xpm','jpg']"
"-sUSE_WEBGL2=1"
"-sINITIAL_MEMORY=33554432"
"--profiling"
"-sDISABLE_EXCEPTION_CATCHING=0"
"-sFETCH=1"
"-sLLD_REPORT_UNDEFINED=1"
"-sFORCE_FILESYSTEM=1"
"-lidbfs.js"
"-sWASM=0"
"-sTOTAL_MEMORY=60MB"
)
add_pc_dependencies(sdlcpp libssl)
add_pc_dependencies(sdlcpp libcrypto)
add_pc_dependencies(sdlcpp libcurl)
target_link_directories(sdlcpp PUBLIC ${CMAKE_SOURCE_DIR}/external/emscripten/install/lib)

set(EMSCRIPTEN_PACKAGER "${EMSCRIPTEN_ROOT_PATH}/tools/file_packager")
```

**Version of emscripten/emsdk:**
```
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 2.0.27 (7e538a419c3649f3a540a57beab347aa8f6c6271)
clang version 14.0.0 (/srcdest/llvm-project 78e87970af888bbbd5652c31f3a8454e8e9dd5b8)
Target: wasm32-unknown-emscripten
Thread model: posix
InstalledDir: /opt/emscripten-llvm/bin
```

Unfortunately I've got the following error when building my project with emscripten.
Does anyone has a clue what I could do ?

```
