IPPsc decode function makes buffer corrupted

Given_L_ — Thu, 25 May 2017 08:24:49 GMT

hello,

When using IPP library to decode EVS codec package with 128k bitrate, the app buffer is corrupted in function e9_Copy ().

The test case is running on Linux x86_64 platform.

The version of IPP I am using:

IPPSP: ippSP AVX (e9) Sep 2 2016 9.0.2 (r49804).PVSDK 1.2.1
IPPSC: ippSC AVX (e9) Mar 24 2017 9.0.2 (r49804).PVSDK 1.5.0

>>Hardware watchpoint 2: (FILE*)*0x3689d90

Old value = (FILE *) 0xfffffffffbad2c84

New value = (FILE *) 0x1c2c84

0x0000000001b5eca6 in e9_Copy ()

(gdb) bt

#0 0x0000000001b5eca6 in e9_Copy ()

Hi,

Hi,

Is this issue the same as this thread https://software.intel.com/en-us/forums/intel-integrated-performance-primitives/topic/734593? If so, can you combine this with the earlier one? Seems it is a PVSDK problem, and we no longer support IPPSC.

The decoder requires more stack than the encoder
