http://d.puremagic.com/issues/show_bug.cgi?id=8258 Summary: Delegates do not respect default parameters Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: regression Priority: P2 Component: DMD AssignedTo: nobody@puremagic.com ReportedBy: eco@gnuk.net --- Comment #0 from Brad Anderson <eco@gnuk.net> 2012-06-17 02:08:40 PDT --- This apparently works in dmd 2.059: void foo(void delegate(int i, bool yes = true) dg) { dg(1); } void main() { void inner(int i, bool yes = true) { } foo(&inner); } but no longer works in dmd git HEAD 2.060. I'm filing this on behalf of someone in IRC. Aldacron may also know something about it too. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

I don't know if it compiles as-is or not, but I've had two Derelict bug reports now with the following error using dmd master: ---- Error: expected 3 function arguments, not 2 ---- In each case, the offending line is a call to a delegate that accepts a default parameter. I didn't want to report a bug until there was a reduced test case, but I don't want to mess around with compiling dmd from git. So I posted that piece of code hoping that a Derelict user would try it out with their dmdgit version to see what happens. It may, or may not, trigger the regression. I've no idea. I was waiting for the beta release if no one got to it before then. But, since it's here, if anyone can see if the code works or not with git dmd... -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

Posted in reply to Brad Anderson | http://d.puremagic.com/issues/show_bug.cgi?id=8258 --- Comment #3 from Kenji Hara <k.hara.pg@gmail.com> 2012-06-18 18:55:22 PDT --- I think this *regression* is introduced by fixing bug 3866. Now all indirect calls do not consider default arguments even if it is written in type signature. I didn't join the discussion, but it seems to me that current *fix* is too conservative way - it rejects some useful cases like this. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
