Hi,

Best regards,

Ämne: [erlang-questions] error with xref and on_load functions

Hi all,
I have a problem running xref on modules with `on_load` functions, for example, giving this module:

-module(xreftest).
-on_load(init/0).

init() ->
  ok.

if we run xref:

1> c(xreftest, [debug_info]).
{ok,xreftest}
2> xref:d(".").
[{deprecated,[]},
 {undefined,[]},
 {unused,[{xreftest,init,0}]}]

we get an `unused` warning for init/0 but it is actually used on load.

Is this a known issue?

Thanks
