Re: [Dev-C++] -fvtable-thunks and CRASH!

[Daniel G. <sp...@ho...>]

what do you mean by crash? does the machine freeze, or do you get an illegal 
operation error or what?

A proper one version:

#include <iostream>
#include <sstream>

int main()
{
 using std::stringstream;
 using std::endl;

 stringstream s;
 s << endl;

 return 0;
}


With GCC 3.2 it doesn't crash but it produces:

C:\c>g++ -fvtable-thunks temp.cpp -o temp
cc1plus.exe: warning: -fvtable-thunks is no longer supported

C:\c>temp

C:\c>

Re: [Dev-C++] -fvtable-thunks and CRASH!

[Carlos d. M. <cg...@wo...>]

Because GCC3.2 compiles with thunks as default.
