Issue ID: 16454
Summary: Return in the body of a foreach in a constructor
backed by opApply corrupts the object
Product: D
Version: D2
Hardware: x86_64
OS: Mac OS X
Status: NEW
Severity: major

import std.stdio;
struct OpApply {
int opApply(int delegate(int) cb) {
return cb(42);
}
}
struct Bolinha {
int a;
this(ref OpApply moviadao) {
foreach(int b; moviadao) {
this.a = b;
return;
}
}
};
void main() {
import std.stdio;
OpApply range;
writeln(Bolinha(range).a);
}
The expected print result was 42. But I get a random memory garbage instead.
The following minor modification in main will 'fix' the issue:
void main() {
import std.stdio;
OpApply range;
Bolinha littleBall = Bolinha(range);
writeln(littleBall.a);
}
