vslCopyStreamState fails

[Guillaume_A_]

Hello,

Since I upgraded MKL from 2024.0.0 to 2025.1.0 I observe crashes around the vslCopyStreamState method.

This simple program will fail on Linux OS:

#include <iostream>
#include <mkl_vsl.h>

int main()
{
    unsigned int scrambledSobolMaxBit = 32;
    unsigned int dimension = 399;

    int z = 0;
    for (; z < 100; z++)
    {
        std::cout <<"z:" << z <<"\n";

        unsigned int nbParameters = 3 + scrambledSobolMaxBit * dimension;
        unsigned int* parameters = new unsigned int[nbParameters];
        
        int k = 0;
        parameters[k++] = dimension;
        parameters[k++] = VSL_USER_QRNG_INITIAL_VALUES;
        parameters[k++] = VSL_USER_DIRECTION_NUMBERS;
        for (; k < nbParameters; k++)
        {
            parameters[k] = 0;
        }

        VSLStreamStatePtr rngState;
        if (vslNewStreamEx(&rngState, VSL_BRNG_SOBOL, nbParameters, parameters) != VSL_STATUS_OK)
        {
            std::cout <<"fail to vslNewStreamEx rngState" <<"\n";
            return 1;
        }
        VSLStreamStatePtr tempState;
        if (vslNewStreamEx(&tempState, VSL_BRNG_SOBOL, nbParameters, parameters) != VSL_STATUS_OK)
        {
            std::cout <<"fail to vslNewStreamEx tempState" <<"\n";
            return 1;
        }
        delete[] parameters;
        std::cout <<"\t0\n";

        if (vslCopyStreamState(tempState, rngState) != VSL_STATUS_OK)
        {
            std::cout << "\t0\t"<< "\tfail to copy streamState" <<"\n";
            return 1;
        }
        
        // no prb if use below commented code
        /*
        if (vslDeleteStream(&tempState) != VSL_STATUS_OK)
        {
            std::cout << "\t0\t"<< "\tfail to vslDeleteStream" <<"\n";
            return 1;
        }
        if (vslCopyStream(&tempState, rngState) != VSL_STATUS_OK)
        {
            std::cout << "\t0\t"<< "\tfail to vslCopyStream" <<"\n";
            return 1;
        }
        */

        std::cout << "\t1\n";

        vslDeleteStream(&rngState);
        vslDeleteStream(&tempState);
    }
    return 0;
}

 The program crashs during the first vslCopyStreamState and show the msg: 

free(): invalid pointer
Aborted (core dumped)

Useful infos:

Compilation options:
-DISOLATION_AWARE_ENABLED -std=gnu++17 -m64 -mavx -axCORE-AVX2,CORE-AVX512 -fthreadsafe-statics -fexceptions -frtti -fomit-frame-pointer -fno-strict-aliasing -O0 -g2 -gdwarf-2 -fPIE -MD -MT

Link options:

Cpuinfo:
  vendor_id : AuthenticAMD
  model name : AMD EPYC-Rome Processor

OS:
  Red Hat Enterprise Linux release 9.5

Env:
  gcc == 13.1.0
  gxx == 13.1.0
  dpcpp_linux-64 == 2025.0.4
  mkl-static == 2025.1.0

Fun facts:

• the program works fine with dimension <= 398.
• the program works fine if comment the first std::cout (line 12).
• the program works fine with the similar method vslCopyStream
• the program works fine with MKL 2024.0.0
• the same code crashs randomly on Windows 11 with an Intel(R) Xeon(R) W-11955M...

Hi Guillaume,

Could you specify how you are running the code? I tried icpx with the compilation and link options which you mentioned and got correct results.

Hi,

Thanks for your answer. 

I am running it the most simple way, in the console: ./myprogram.out on Linux, myprogram.exe on Windows.

Did you run it on Windows or Linux OS? With an AMD or Intel CPU?

Regards,

Guillaume A.

Sorry for making the confusion, by 'running' I meant mainly compiling. I used Linux.

[Guillaume_A_]

Oh ok, my whole compilation/link commands:

/Console # /root/bin/mf-current/bin/icpx -DISOLATION_AWARE_ENABLED -I/root/bin/mf-current/x86_64-conda-linux-gnu/include/c++/13.1.0 -I/root/bin/mf-current/x86_64-conda-linux-gnu/include/c++/13.1.0/x86_64-conda-linux-gnu -I/root/bin/mf-current/x86_64-conda-linux-gnu/sysroot/usr/include -I/root/bin/mf-current/include -std=gnu++17 -m64 -mavx -O0 -g2 -gdwarf-2 -fPIE -o myprogram.cpp.o -c myprogram.cpp
/Console # /root/bin/mf-current/bin/icpx -pie -m64 --sysroot=/root/bin/mf-current/x86_64-conda-linux-gnu/sysroot -static-libgcc -static-libstdc++ -static-intel myprogram.cpp.o -o myprogram.out -Wl,--start-group /root/bin/mf-current/lib/libmkl_intel_lp64.a /root/bin/mf-current/lib/libmkl_sequential.a /root/bin/mf-current/lib/libmkl_core.a -Wl,--end-group -lpthread -ldl

Note that I removed some option to keep it simple, but I still reproduce the crash.

gcc, g++, mkl and dpcpp have been installed with conda (miniforge).

Hi, I eventually reproduced the issue and we will work on it internally. I'll post here with any news.

[Guillaume_A_]

Hello, any news on this?

[Aleksandra_K]

Hi,

I confirmed that work on this issue is in progress. I'll post here once there are updates.
