Issue ID: 21301
Summary: Wrong values being passed as variadic arguments
Product: D
Version: D2
Hardware: x86_64
OS: Linux
Status: NEW
Severity: regression
Priority: P1
Component: dmd

Since DMD 2.084.0, the following code fails:
```
void main()
{
void func(T...)(T args){
// here args[1] is received as [0, 0, 64, 64, 38, 86, 0, 0, 1,
2, 3, 4]
assert(args[1][0 .. 12] == [1,2,3,4,5,6,7,8,9,10,11,12]);
}
func(
ubyte(0),
cast(ubyte[12])[1,2,3,4,5,6,7,8,9,10,11,12],
cast(float[3])[1f,2f,3f],
0f,
0f,
0f,
0f,
0f,
0f,
0f,
0f,
0f,
uint(0),
[0,1,2,3,4],
uint(0),
);
}
```
This code works correctly on DMD 2.083.1, but fails on 2.084.0 and
2.084.1-beta.
Adding or removing arguments in the func call (like adding one more 0f value)
makes func work correctly and pass its assert.
Changing the value of the first ubyte(0) changes the data received as args[1]
(but still fails on the assert)
args[1] seems to be shifted by 8 bytes
