>Description:
I am encountering strange crashes in the libstdc++ code.
The included program crashes in the first << operator giving a "Illegal instruction (core dumped)"
The callstack shows that it crashed in: bits/locale_facets.h
At line 778, which is one of the num_put::put() functions.
It seems to be having an invalid virtual base pointer or something to do with the virtual table.
This is a simple example created after a larger program encountered this problem, even with other stream types.
>How-To-Repeat:
#include <iostream>
#include <sstream>
int main(int argc, char* argv[])
{
std::basic_ostringstream<char> os;
os << 5.3;
std::cout << os.str() << std::endl;
return 0;
}
