Summary: No template instantiation backtrace printed trying to use writefln on a const or immutable object reference Product: D Version: D2 Platform: x86 OS/Version: Windows Status: NEW Keywords: diagnostic Severity: normal Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: s...@iname.com --- Comment #0 from Stewart Gordon <s...@iname.com> 2012-03-24 17:52:11 PDT --- DMD 2.058, Win32 ---------- import std.stdio; class Set(Element) { void show(Element e) { writefln("%s", e); } } void main() { Set!(const(Object)) set2; } ---------- C:\Users\Stewart\Documents\Programming\D\Tests\bugs>dmd hashset1.d d:\dmd2\windows\bin\..\..\src\phobos\std\format.d(1858): Error: template instance formatObject!(LockingTextWriter,const(Object),char) formatObject!(LockingTextWriter,const(Object),char) does not match template declaration formatObject(Writer,T,Char) if (hasToString!(T,Char)) ---------- main instantiates Set Set instantiates writefln writefln instantiates File.writefln File.writefln instantiates formatGeneric formatGeneric instantiates formatValue formatValue tries to instantiates formatObject but fails Despite this chain of template instantiations, no backtrace is printed. Consequently, it took me ages to find what in my code was triggering it in order to produce this reduced testcase. Fixing issue 1824 will invalidate this testcase, but won't fix the underyling compiler bug, which could potentially bite in other ways. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
