Bug ID: 86130
Summary: Expect SIGBUS but program just silently exits
Product: gcc
Version: 8.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

Hi guys,
My first post here, hope I do things right.
The following code snippet just exits the program silently rather than
generating SIGBUS as you would expect it to. I don't think what doing that is
appropriate.
clang *does* generate SIGBUS, and although the code below is, strictly
speaking, UB, I don't think gcc should behave as it does, for obvious reasons.
OK, here's the code:
#include <iostream>
int main()
{
char *p = (char *) nullptr;
std::cout << "Watch the " << p << "birdie" << std::endl;
return 0;
}
And here's the output (note: no SIGBUS):

Sounds like an easy fix. Thanks.
