Code:
import std.stdio;
struct S {
short[4] x;
this(short[4] args...) {
x[] = args[];
}
bool opEquals(in S s) const {
for (auto i=0; i < 4; i++) {
if (this.x[i] != s.x[i])
return false;
}
return true;
}
}
void main() {
assert(S(1,2,3,4) == S(1,2,3,4));
}
Output: with dmd -m64, the assertion fails. Inserting writeln's show that the elements of s in opEquals() are garbage values. Trying to print out the entire array of this or s causes a segfault.
On dmd -m32, there is no problem.
Not sure if this is related to bug 5570.

P.S. Changing the static array to int[4] for some reason makes the problem go away. Don't know how this is relevant, but might be useful to track down the bug in the compiler.

Can no longer reproduce this bug in latest git dmd, may have been fixed?

Seems to work with DMD 2.060 (and trunk) both with m32 and m64

I think we can close this issue as for now although I am not sure what certain Commit fixed it.
