[erlang-bugs] erlang:halt bug

[Martin Bjorklund]

Hi,

Doing

  erlang:halt(lists:duplicate(199,$a)).

halts the emulator just as it should.  But

  erlang:halt(lists:duplicate(200,$a)).

fails with badarg.

The reason of that the halt_1 bif checks if the string is longer than
199 bytes; if it is it returns badarg.

The documentation doesn't mention this at all.

IMO, the bif should truncate the string if necessary.

I noted that the code in init.erl truncates this in one case...
