All I can say is that initialising both lambda and w (from CRAN
version) solved the issue for me. As a matter of fact, I did see
another message about uninitialised values, but the back trace was
empty (no function names, I mean), which means that the problem is
somewhere else.

If you set up a public repo (GitHub or similar) where everyone can see
your current code base and changes made, it would be easier to help.
It would be even easier if you check your changes using a public build
system and share the results here. I don't know whether win-builder
uses valgrind, but you can use r-hub (https://github.com/r-hub/rhub)
by Gábor Csárdi. There is a function rhub::check_with_valgrind which
requires no further explanation.
