<pre>The following code compiles cleanly with clang with '-Weverything':
--------------------
int main()
{
int x = 3;
x += 1.234;
return x;
}
--------------------
It is expected to issue a -Wfloat-conversion warning. For example, gcc 4.9
gives:
--------------------
tmp.cc: In function 'int main()':
tmp.cc:4:7: warning: conversion to 'int' from 'double' may alter its value
[-Wfloat-conversion]
x += 1.234;
--------------------</pre>
