When a ref is created before performing a receive that will only
receive message containing that ref, there is a compiler optimization
to avoid scanning messages that can't possible contain the newly
created ref.
Magnus Lång pointed out that the implementation of the optimization
is flawed. Exceptions or recursive calls could cause the receive
operation to scan the receive queue from a position beyond the expected
message (that is, the message containing the ref would never be
matched out). See the receive_opt_exception/1 and receive_opt_recursion/1
test cases in receive_SUITE.
It turns out that we can simplify the implementation of the
optimization while fixing the bug (suggested by Magnus Lång). We
actually don't need the c_p->msg.mark field. It is enough to have
c_p->msg.saved_pos; if it is non-zero, it is a valid position in the
message qeueue. All we need to do is to ensure that we clear
c_p->msg.saved_pos when a receive is exited normally or abnormally.
We can clear c_p->msg.saved_pos in JOIN_MESSAGE(), since it is called
both when leaving a receive because a message matched and because there
was a timeout and the 'after' clause was executed. In addition, we
need to clear c_p->msg.saved_pos when an exception is caught.

The 's' operand overloads the tags for pids and ports to represent
X and Y registers, respectively. At load time, refuse to load the
module if the "literal" term is not a pid or port, as it would be
interpreted as a register.
This does not happen with normally compiled code, but it can happen
if the compiler (or beam_asm) is abused like in the following example:
make_bad() ->
Pid = self(),
Forms = [{attribute, 0, module, bad_s_operand},
{attribute, 0, export, [{test, 0}]},
{function, 0, test, 0,
[{clause, 0, [], [],
[{call,0,{atom,0,tuple_size},[{integer, 0, Pid}]}]}]}],
{ok, Module, Bin} = compile:forms(Forms, [no_copt,no_postopt,report_errors]),
code:load_binary(Module, "bad_s_operand.erl", Bin).
With this commit applied, the following message will be printed
when make_bad() is run:
=ERROR REPORT==== 10-Nov-2017::14:47:59 ===
Loading of bad_s_operand.erl failed: badfile
=ERROR REPORT==== 10-Nov-2017::14:47:59 ===

the term '<0.60.0>' would be confused with a register

As of commit 12b379 many of the reasons displayed after
"Analysis failed with error:"
erroneously include a call stack. The bug is now corrected.
The bug was pointed out in
http://erlang.org/pipermail/erlang-questions/2017-October/093838.html.
