for missing return statements in the called/callee function? For a<br>
missing return clang generates SIGILL while GCC is returning something<br>
ABI-dependent IIRC.<br>
<br>
E.g. this causes SIGILL on clang and runs just fine on GCC:<br>
```<br>
int foo(int i) {<br>
if(i) {<br>
return 1;<br>
}<br>
}<br>
<br>
int main() {<br>
foo(0);<br>
}<br>
