LZO : diffrent decompression thread number produces different result

yellow9611

OS: RedHat Enterprise Linux 4.0 U6 (Linux 2.6.9-67.ELsmp x86_64)
CPU:IntelXeon (2 socket, quad core, No HT)
gcc: 4.2.2
ipp: 6.0.1, dynamic library

I compressed the raw data using LZO method 'IppLZO1XMT',
but different decompression thread number produced different decompression result.

Is it a bug of Ipp LZO data compression library?

Other clue:
Supposing the compression thread numberis N,
If the raw data size is greater or equan than 256 * N, the issue could be reproduced.

Hi! Yes, you're right, this is a bug. It will be fixed in the nearest IPP 6.1 update.

Thanks!

Just FYI: has been fixed in IPP 6.1 Gold Update 1 in August, last year.
