http://d.puremagic.com/issues/show_bug.cgi?id=654 Summary: Const string member using implicit type inference gives garbage in certain situation Product: D Version: 0.176 Platform: PC OS/Version: Windows Status: NEW Severity: normal Priority: P3 Component: DMD AssignedTo: bugzilla digitalmars.com ReportedBy: chris inventivedingo.com Suppose we have a class (call it A), with a const member called MY_CONST_STRING that is initialised to a char array using implicit type inference. Suppose also that at some point in the code we refer to it as "A.MY_CONST_STRING". Then, if we print "MY_CONST_STRING" from within the class A, garbage will be produced. However, if we never refer to "A.MY_CONST_STRING" anywhere, then printing "MY_CONST_STRING" will work as expected (without producing garbage). It seems to be necessary that the member is a char array, and that implicit type inference is used. (Declaring it as static const char[] MY_CONST_... will cause everything to work.) This is easier to see in code: --------- testbug.d --------- import std.stdio; class A { static const MY_CONST_STRING = "hello"; this() { // This will either print garbage or throw a UTF exception. // But if never_called() is commented out, then it will work. writefln("%s", MY_CONST_STRING); } } void never_called() { // This can be anything; there just needs to be a reference to // A.MY_CONST_STRING somewhere. writefln("%s", A.MY_CONST_STRING); } void main() { A a = new A(); } --------- D:\D>dmd -run testbug ♣ Error: 4invalid UTF-8 sequence D:\D> --
