http://d.puremagic.com/issues/show_bug.cgi?id=4746 Summary: CTFE regression + CTFE/normal execution differences (splitlines). Product: D Version: D2 Platform: x86_64 OS/Version: Windows Status: NEW Severity: normal Priority: P2 Component: DMD AssignedTo: nobody@puremagic.com ReportedBy: peter.alexander.au@gmail.com --- Comment #0 from Peter Alexander <peter.alexander.au@gmail.com> 2010-08-28 14:06:28 PDT --- This is two bugs at once. The first is a regression in 2.048 from 2.047 where splitlines is no longer CTFEable. The second is that, in 2.047, splitlines doesn't work when CTFE'd. // 2.048 void main() { static auto s = splitlines("a\nb"); // Error: not CTFEable writeln(s[0]); } // 2.047 void main() { auto s = splitlines("a\nb"); // Note non-static writeln(s[0]); // Writes 'a'... correct! } // 2.047 void main() { static auto s = splitlines("a\nb"); // CTFE'd this time writeln(s[0]); // Writes nothing... incorrect! } Note that the 2.048 was run on Windows 7 and the 2.047 was run on Mac OS X Snow Leopard. Also note that string.split appears to have the same issue (was CTFEable in 2.047, but not in 2.048). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

This bug was fixed in 2.048, and it now (correctly) says that it cannot compile it. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
