[erlang-bugs] system_info(nif_version) does not work

[PAILLEAU Eric]

Thinking to this ...

-since erlang:system_info(nif_version) -> "17.4".

-spec erlang:system_info
	(allocated_areas) -> [ tuple() ];

		snip --- snip

   	(nif_version) -> string();

		snip --- snip
	(wordsize | {wordsize, internal} | {wordsize, external}) -> 4 | 8.

This could also be pickup by doc generation, BTW...
