Segmentation fault when reading variables in pointed function

I have the following pieces of code: (Note: the codes are simplified and changed a lot as I can't share the data)

exercise.cpp

#include "some_api.h"

int main(int argc, char** argv)
{
    VExtension ve;
    extension_init(&func, &ve);
    return 0;
} 

some_api.h

bool func(int const& a, void* const& b, VExtension* const& v)
{
    std::cout << a << b << std::endl;
}

api.h

typedef int (func_t)(int c, void* p, VExtension* v)

file.cpp

#include "api.h" // this is included implicitly

extern "C" int extension_init(func_t* F, VExtension* v)
{
    intptr_t ver = 7;
    F(1, (void*)ver, v);
}

So, when F is called func is called from some_api.h, but Seg Fault appears when trying to output the values a and b. Static analyzer gives the following error message:
