Main pieces of code that are causing are the following: image

@herumi do you have any idea on how I would mitigate this issue?

herumi commented 1 year ago

What CPU/OS/compiler options do you use? And because I don't know test/blsct/arith/g1point_tests.cpp(72), I can't check it.

herumi commented 1 year ago

If the problem occurs only if using a libbls384_256.a built by https://github.com/herumi/bls/blob/dev/Makefile.onelib , then please specify -DMCL_MAX_BIT_SIZE=384 to your project.

herumi commented 1 year ago

All tests of mcl/bls run with -fsanitize=address. The constructor of mcl/bls does not clear the value. Does your code correctly initialize a value?

We are seeing the following error when building with -fsanitize=memory:

Adding -DMCL_MAX_BIT_SIZE=384 does not fix the issue.

mcl_initializer.cpp:

#include <blsct/arith/mcl_initializer.h>

void MclInitializer::Init()
{
    boost::lock_guard<boost::mutex> lock(MclInitializer::m_init_mutex);
    static bool is_initialized = false;
    if (is_initialized) return;

    if (mclBn_init(MCL_BLS12_381, MCLBN_COMPILED_TIME_VAR) != 0) {
        throw std::runtime_error("blsInit failed");
    }
    mclBn_setETHserialization(1);

    is_initialized = true;
}

mcl_initializer.h:

#include <mcl/bn_c384_256.h>
#include <boost/thread/lock_guard.hpp>
#include <boost/thread/mutex.hpp>

class MclInitializer
{
public:
    static void Init();

private:
    inline static boost::mutex m_init_mutex;

I think that this is the same reason at https://github.com/herumi/mcl/issues/167#issuecomment-1338454691 .
