Possibly-related memory corruption issue #43
Description
I guessing this is probably a dmd issue, and filed it as 19825. But I'm posting here too, just in case std_data_json is part of the problem, or anyone here could help find the exact compiler problem:
dub.sdl:
name "test"
dependency "std_data_json" version="==0.18.3"
main.d:
import std.stdio;
import stdx.data.json;
enum rawJson = `
{
"rootPackage": "vibe-d",
"targets": [
{
"rootConfiguration": "vibe-core"
}
]
}
`;
void yap(T...)(lazy T args)
{
writeln(args);
}
struct Foo
{
int a;
string name;
}
Foo makeFoo()
{
Foo foo;
auto root = rawJson.toJSONValue;
foo.name = root["rootPackage"].toString.idup;
writeln(foo.name);
yap(root["targets"][0]["rootConfiguration"]);
return foo;
}
void main(string[] args)
{
auto foo = makeFoo();
writeln(foo.name); // Garbled output, then an exception
}result:
$ dub -q
vibe-d
vibe-core
[...garbled data here...]uncaught exception
