But this is not a bug anyway, your code has undefined behaviour. You
cannot use m
Dear gnu:
Here is code:
#include
#include
#include
class segment_fault
{
std::string str;
int a;
float *b = nullptr;
};
int main()
{
std::vector segments;
segment_fault sf;
memset(&sf,0,sizeof(sf));
std::cout << "segment's size is: "<< sizeof(segment_fault) <
