To make it compiles without issue -> Remove the "package.d" from compiling source


Since the modules have object defined such class "XmlAttribute(S = string) : XmlNode!S". The package.d is just an import of all modules with some alias as below. Still not able to dustmite the problem

public import pham.xml_exception;
public import pham.xml_util;
public import pham.xml_buffer;
public import pham.xml_string;
public import pham.xml_entity_table;
public import pham.xml_new;
public import pham.xml_parser;
public import pham.xml_reader;
public import pham.xml_writer;
public import pham.xml_xpath;


/** For utf8 encoded string
*/
alias XmlAttributeA = XmlAttribute!string;
alias XmlCDataA = XmlCData!string;
alias XmlCommentA = XmlComment!string;
...

/** For utf16 encoded string
*/
alias XmlAttributeW = XmlAttribute!wstring;
alias XmlCDataW = XmlCData!wstring;
alias XmlCommentW = XmlComment!wstring;
...

The leaf node in the stack trace is object.TypeInfo_Array.toString(), and
looking at that code
(https://github.com/dlang/druntime/blob/2cc13ead1e7e535ef8ebd1f600d4ffb508a93f98/src/object.d#L532):

override string toString() const { return value.toString() ~ "[]"; }

This will fail if value is null. Is it null though?

unittest {
    auto a = typeid("");
    import std.stdio;
    writeln(a.toString());
}

> immutable(char)[]

Doesn't look like it.

unittest {
    auto a = typeid("");
    assert(a.value !is null, "a.value is null!");
}

> [unittest] a.value is null!

Uhm...

It seems something is special cased when handling TypeInfo, so that the code in toString() doesn't run at that point. For whatever reason, this short-circuiting doesn't happen inside DMD, and so it crashes.

(In reply to Simen Kjaeraas from comment #2)
> The leaf node in the stack trace is object.TypeInfo_Array.toString()

I think that's a wrong lead due to a faulty stacktrace. The interesting bit is

> core.exception.RangeError@dmd\root\array.d(226): Range violation

That comes from an invalid index into a dmd.root.array.Array instance (https://github.com/dlang/dmd/blob/v2.090.0/src/dmd/root/array.d#L226).

The next frame in the stacktrace seems reasonable, pointing to https://github.com/dlang/dmd/blob/v2.090.0/src/dmd/dsymbolsem.d#L3655:

FuncDeclaration fdc = cd.vtbl[vi].isFuncDeclaration();

suggesting an invalid vi index.

Btw, this issue showing up like this is only possible because the DMD 2.090.0 Windows builds were debug builds, that's why we have enabled bounds checks, debuginfos and even line infos.
