Are you using LTO? What rustc version are you using?

[Ludea]

rust version : 1.92 and I don't use LTO

Historically this has been highly dependent on compiler options to reproduce and try to debug. Can you share the exact command line and flags you're using to build with Wasmtime? (and the project too perhaps?)
