In:

LzmaDec_TryDummy() was called before to exclude LITERAL and MATCH-REP cases.
So first symbol can be only MATCH-NON-REP. And if that MATCH-NON-REP symbol
is not END_OF_PAYALOAD_MARKER, then function returns error code.
}
Processing:
first LZMA symbol will be decoded in any case
All checks for limits are at the end of main loop,
It will decode new LZMA-symbols while (p->buf < bufLimit && dicPos < limit),
RangeCoder is still without last normalization when (p->buf < bufLimit) is being checked.
Out:

HISTORY of the LZMA SDK
-----------------------
18.05 2018-04-30
-------------------------
- The speed for LZMA/LZMA2 compressing was increased
by 8% for fastest/fast compression levels and
by 3% for normal/maximum compression levels.
- Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in
Windows 10 because of some BUG with "Large Pages" in Windows 10.
Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).
- The BUG was fixed in Lzma2Enc.c
Lzma2Enc_Encode2() function worked incorretly,
if (inStream == NULL) and the number of block threads is more than 1.
18.03 beta 2018-03-04
-------------------------
- Asm\x86\LzmaDecOpt.asm: new optimized LZMA decoder written in asm
for x64 with about 30% higher speed than main version of LZMA decoder written in C.
- The speed for single-thread LZMA/LZMA2 decoder written in C was increased by 3%.
- 7-Zip now can use multi-threading for 7z/LZMA2 decoding,
if there are multiple independent data chunks in LZMA2 stream.
- 7-Zip now can use multi-threading for xz decoding,
if there are multiple blocks in xz stream.
18.01 2019-01-28
-------------------------
- The BUG in 17.01 - 18.00 beta was fixed:
XzDec.c : random block unpacking and XzUnpacker_IsBlockFinished()
didn't work correctly for xz archives without checksum (CRC).
18.00 beta 2019-01-10
-------------------------
- The BUG in xz encoder was fixed:
There was memory leak of 16 KB for each file compressed with
xz compression method, if additional filter was used.
17.01 beta 2017-08-28
-------------------------
- Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.
7-Zip now uses additional memory buffers for multi-block LZMA2 compression.
CPU utilization was slightly improved.
- 7-zip now creates multi-block xz archives by default. Block size can be
specified with -ms[Size]{m|g} switch.
- xz decoder now can unpack random block from multi-block xz archives.
- 7-Zip command line: @listfile now doesn't work after -- switch.
Use -i@listfile before -- switch instead.
- The BUGs were fixed:
7-Zip 17.00 beta crashed for commands that write anti-item to 7z archive.
17.00 beta 2017-04-29
-------------------------
- NewHandler.h / NewHandler.cpp:
now it redefines operator new() only for old MSVC compilers (_MSC_VER < 1900).
- C/7zTypes.h : the names of variables in interface structures were changed (vt).
- Some bugs were fixed. 7-Zip could crash in some cases.
- Some internal changes in code.
16.04 2016-10-04
-------------------------
- The bug was fixed in DllSecur.c.
