https://issues.dlang.org/show_bug.cgi?id=20471 --- Comment #1 from apham <apz28@hotmail.com> --- 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; ... -- |

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. -- |

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. -- |

https://issues.dlang.org/show_bug.cgi?id=20471 --- Comment #4 from kinke <kinke@gmx.net> --- 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. -- |
