Precomp CRC error

[tanerjames]

Hi,

My problem is precomp when decompressing.

arc.ini:

[External compressor:precomp]
header = 0
packcmd   = precomp -intense -c-  {options} -o$$arcpackedfile$$.tmp  $$arcdatafile$$.tmp
unpackcmd = precomp -o$$arcdatafile$$.tmp -r $$arcpackedfile$$.tmp

compress:

arc a -ep1 -r -ed -lc512 -ld512 -mt1 -mprecomp+delta+lzma:a1:mfbt4:d158m:fb273:mc1000:lc8 "C:\pack\test.arc" "C:\pack\test\*"


100.00% - New size: 1033857462 instead of 1760634392


Done.
Time: 15 minutes, 45 seconds


Recompressed streams: 3894/6964
GZip streams: 0/6
PNG streams: 53/227
PNG streams (multi): 50/63
zLib streams (intense mode): 3791/6668


You can speed up Precomp for THIS FILE with these parameters:
-zl38,64,68,98 -d0


Errorlevel=0
Compressed 1 file, 1,760,634,392 => 1,044,793,889 bytes. Ratio 59.34%
Compression time: cpu 400.69 sec/real 1354.96 sec = 30%. Speed 1.30 mB/s
All OK

decompress with unarc.exe:

unarc.exe x -dpunpacked\ test.arc

result:
ERROR: file unpacked\tscex15V1.cpk failed CRC check

decompress with arc.exe:

arc.exe x -dpunpacked\ test.arc

result:
arc.exe: wclose: invalid argument (Bad file descriptor)
ERROR: CRC failed in "unpacked\tscex15V1.cpk". File is broken.

I use a different version of Precomp (0.38, 0.40, 0.41, 0.42, 0.43), but same problem.

I changed switch of Precomp:
precomp -intense -c- -t-j
precomp -intense -t-j
precomp -intense
precomp -intense -mjpeg- -t- -c-

result: CRC error


and last switch:
precomp -c-

result: no CRC error

This CRC problem occurs when some files in -intense mode.


What is the problem?


Thanks.
