<pre>Using clang r253159, the code itself does not use exception handling itself:
#include <cmath>
#include <iostream>
using namespace std;
unsigned int f2(double x)
{
double result = 0.0133333 * pow(x, 3) - 0.8 * pow(x, 2) + 21.6667 * x + 90;
return static_cast<unsigned int>(result);
}
int main()
{
double input;
while (1) {
cout << "Enter a value: ";
cin >> input;
cout << "Calculated: " << f2(input) << endl;
}
return 0;
}
λ clang-cl /EHsc -fmsc-version=19 test.cpp
λ ./test.exe
zsh: segmentation fault ./test.exe
Remove /EHsc and its fine:
λ clang-cl -fmsc-version=19 test.cpp
λ ./test.exe
Enter a value:
^C
Using VS2015 on Win10 x64.</pre>
