The temporary child specs are never removed from the supervisor's state, and
have they're MFA component set to {M, F, undefined} instead of the MFA passed
in the supervisor:start_child/2 call. Subsequent calls to supervisor:restart_child/2
may crash. Stack trace example:
{badarg,[{erlang,apply,[gen_server,start_link,undefined]},
{supervisor,do_start_child,2},{supervisor,handle_call,3},
{gen_server,handle_msg,5},
{proc_lib,init_p_do_apply,3}]}

The r11 option is no longer supported by the compiler (silently
ignored).

In a file containing declarations and comments without any empty lines
between them, the recomment_forms() function would associate a
multi-line comment with the declaration above it rather than the one
following it. (Thanks to Richard Carlsson.)
This bug has been reported several times. It was corrected by Kostis
Sagonas, but the fix didn't make into the R14B02 release.

Add new option <c>src_tests</c> to systools:make_script and
systools:make_tar. The old option <c>no_module_tests</c> is now
ignored as this is the default behaviour.

It is not needed because it can be trivially calculated using
gb_trees:size/1.
|
|
|
|
Calling a BIF thaf is called as a function (such as process_info/{1,2})
would leave a non-zero value in c_p->cp, which would lead to
duplicate entries in the stacktrace.
|
|
For some historical reason, the transformation of a func_info/3
instruction to the internal i_func_info/4 instruction is more
involved than it needs to be. Remove the gen_func_info() function
in the loader and use a simple transformation.

The compiler (sys_core_fold) tries to avoid constructing tuples
in case expressions. The following code:
c(A, B) ->
case {A,B} of
{ok,X} -> X;
{_,_} -> error
end.
will be rewritten so that no tuple is built. If a clause
requires a tuple to be built as in this code:
c(A, B) ->
case {A,B} of
{ok,X} -> X;
V -> V %The tuple will be built here
end.
the tuple will be built in the clause(s) in which it is needed.
If the value returned from the case is not used as in this code:
c(A, B) ->
case {A,B} of
V -> V %Warning: a term is constructed, but never used
end,
ok.
there will be an incorrect warning. Basically, what happens is
that the code is reduced to:
c(A, B) ->
{A,B}, %Warning: a term is constructed, but never used
ok.
and the optimizer sees that the {A,B} tuple can't possibly be used.
Eliminate the warning by adding a 'compiler_generated' annotation
to the tuple.

Since the log_mf_h index file might be read by other processes than
the error handler (e.g. by the rb tool), this file should be updated
atomically. This will avoid hitting the time gap between opening the
file in write mode (and thus emptying the file) and the actual update
with the new contents. To do this, a temporary file is written, and
the file:rename/1 used to replace the real index file.

In the following code:
m(<<Sz:8,_:Sz/binary>>) ->
Sz = wrong.
the Sz variable is supposed to be bound in the function header and the
matching "Sz = wrong" should cause a badarg exception. But what
happens is that the Sz variables seems to be unbound and the matching
succeds and the m/1 function returns 'wrong'.
If the Sz variable is used directly (not matched), it will have
the expected value. Thus the following code:
m(<<Sz:8,_:Sz/binary>>) ->
Sz.
will correctly return the value of Sz that was matched out from
the binary.
