Issue ID: 23126
Summary: wrong result of integer division in presence of assert
within conditional operator expression
Product: D
Version: D2
Hardware: x86_64
OS: Linux
Status: NEW
Severity: enhancement
Priority: P1
Component: dmd
Assignee: [email protected]
Reporter: [email protected]
Found the function divide in a forum post [1]
```div.d
import std.stdio;
import std.conv;
int divide(int dividend, int divisor)
{
return divisor == 0
? assert(false, "You shall not divide by zero")
: dividend / divisor;
}
int main (string [] args)
{
int a = args[1].to!int;
int b = args[2].to!int;
int c = divide (a, b);
writefln!"%d / %d = %d" (a, b, c);
return 0;
}
```
$ dmd div.d
$ ./div 1 2
1 / 2 = 2
Wrong result since dmd 2.097.2, dmd 2.096.1 complains
div.d(6): Error: `return` expression expected
dmd -O produces executable returning correct results.
expected:
$ gdc div.d -o div
$ ./div 1 2
1 / 2 = 0
