In this case I get:

[C/C++ DevTools Support (DWARF)] Loading debug symbols for http://localhost:8080/build/debug_example.wasm (via debug_example.wasm.debug.wasm)...

but never get the other message saying that things have been loaded. There is also not other error in the process of compiling or linking nor on the website, which behaves as expected.

If from the previous command I subtract the -Wl,--whole-archive -lsdf_context -Wl,--no-whole-archive library, things seem to work a symbols are loaded.

Following this guide https://developer.chrome.com/blog/faster-wasm-debugging#debug_fission I'm using the dwarf split command since doing otherwise results in Chrome crashing trying to load the debug information. I followed this guife
