As an addition to my original post: for example,
#include <iostream>
#include <limits>
int main() {
unsigned int maxi = std::numeric_limits<unsigned int>::max();
maxi++;
std::cerr << "Value of maxi after sum: " << maxi << std::endl;
return 0;
}
after compiled with or with -ftrapv g++ generates binary executables
which are exactly the same:
[EMAIL PROTECTED] ~ $ g++ -o ftrapvw ftrapv.cc
[EMAIL PROTECTED] ~ $ g++ -ftrapv -o ftrapv ftrapv.cc
[EMAIL PROTECTED] ~ $ md5sum ftrapv
fa2b15c2dccf7d721ae883cea1e5190e ftrapv
[EMAIL PROTECTED] ~ $ md5sum ftrapvw
fa2b15c2dccf7d721ae883cea1e5190e ftrapvw
What's the problem after all?
Cheers,
Paulo Matos
