>Description:
Division by zero and floating point exceptions are not
caught by a general catch(...) handler. Instead the program
is aborted with the "Floating point exception" message.
>How-To-Repeat:
g++ -fexceptions -O0
include <stdio.h>
int main()
{
try {
printf("hello 1\n");
int r=1;
int k=0;
int j=r/k;
printf("no exception 1\n");
}
catch(...)
{
printf("exception caught 1\n");
}
try {
printf("hello 2\n");
double r=1;
double k=0;
double j=r/k;
printf("no exception 2\n");
}
catch(...)
{
printf("exception caught 2\n");
}
printf("leaving\n");
return 0;
}
