http://d.puremagic.com/issues/show_bug.cgi?id=4867 Summary: Postblit is not usable with const objects Product: D Version: D2 Platform: Other OS/Version: Linux Status: NEW Severity: critical Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: samukha voliacable.com PDT --- struct S { this(this) { } } void foo(ref const S s) { auto s2 = s; } void main() { } Error: function test.S.__cpctor (ref S p) is not callable using argument types (const(S)) const It is not specified how postblit is supposed to interoperate with const/immutable. Tagging the postblit function with 'const' doesn't help (compilation fails with the same error). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=4867 https://github.com/D-Programming-Language/dmd/commit/eb7983c7215b51e5bb719803d48ccf2ed211ab5b Now this issue is resolved, the mutable postblit is called on copied const object. But, this behavior temporarily allows breaking const correctness inside mutable postblit. Therefore, I don't close this issue. Destructor has a similar problem, see bug 4338. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Therefore, I don't close this issue.Consolidated into Issue 8956. Do not close this issue as a duplicate because it is another issue. E.g. it can be closed as WONTFIX if postblits will become qualifier-overloadable. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
