double free or corruption problem..

[Luice]

There was a problem with the code like the following. Is it possible that what is a problem?

ex)
void function(string str1)
{
string str2;
str2 = str1; -->> double free or corruption
}

int main(void)
{
string str = "abcd";
function(str);
}


As a result of try using GDB, There was a problem with the part to be sent using the = as a string string value.

No, that code looks fine to me, assuming you are using std::string anyway.
