'tar_entry()' values are only returned if we specify the 'verbose'
option when calling table/2, which table/1 doesn't do.
Now, it appears that Dialyzer as of OTP 20 is clever enough to realize
that the return type of table/1 must intersect with the return type of
table/2, and so it ignores the fact that table/1 says it returns
strings, and therefore its callers are expected to be dealing with
'tar_entry()' tuples, and never with strings.
This is obviously a mismatch between what the code does and what the
spec says is does, leading to false Dialyzer warnings on code that uses
table/1 (and, presumably, also table/2 when called without
the 'verbose' option.)

beam_validator did not verify that the Y registers were initialized
before executing the following instructions that could cause a GC:
bs_append/8
bs_init2/6
bs_init_bits/6
gc_bif1/5
gc_bif2/6
gc_bif3/7
test_heap/2
That means that, for example, an incorrect optimization that replaced
an 'allocate_zero' instruction with an 'allocate' instruction when it
was not safe, would not be rejected by beam_validtor, but would
instead cause a crash or other undefined behavior at runtime.
Also fix a minor bug in beam_type exposed by the stronger checking.
When compiling from .S files, beam_type did not handle the
init/1 instruction and could produce unsafe code.

Stream ciphers are not valid fro DTLS
|
|
Client will retransmit until server becomes responsive
|
|
The type optimizations for is_record and test_arity checked whether
the arity was equal to the size stored in the type information,
which is incorrect since said size is the *minimum* size of the
tuple (as determined by previous instructions) and not its exact
size.
A future patch to the 'master' branch will restore these
optimizations in a safe manner.

Fix GC bug for HiPE primop bs_put_utf8
|
|
in order to detect incompatible changes in primop interface
(which we just did for bs_put_utf8) and refuse hipe loading.
|
|
by preventing it from doing GC, which generated code relies on.
