IPPsc decode function makes buffer corrupted

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 ()

#1  0x00000000007faabb in e9_post_decoder ()

#2  0x000000000092ccb8 in e9_decoder_LPD ()

#3  0x00000000007e755f in e9_dec_acelp_tcx_frame ()

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
