Think this i a v bug, i have reported as issue #24491 in the v repro.

in psi/StubBase.v:66 change this line:

stub_list.add_stub(mut stub, unsafe { nil })

to:

empty:= unsafe { nil }
stub_list.add_stub(mut stub, empty)

and the seg.fault disapers.

The V issue was fixed https://github.com/vlang/v/issues/24491 with a cgen change.

Can you please check, if that solved this issue too?
