http://d.puremagic.com/issues/show_bug.cgi?id=10682 In fact, all versions of dmd from 2.063.2 up to commit 50a484a60cc3794281a98c51346fc0dfacfc0f24 (Fix Issue 5943 - Power expression optimisation: 2^^unsigned ==> 1<<unsigned) displayed an error message of the form: test.d(3): Error: must import std.math to use ^^ operator and all versions thereafter (that I tested) simply compiles it with no error. Maybe it was an intermittent failure that was quickly fixed, or maybe it only happens with specific compiler flags, or maybe it's Windows-specific? -- 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=10682 OK, must be a Windows-specific problem then. Sorry, can't help you there (don't have a Windows dev machine). :-( -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Usually, a cast to int is inserted during semantic on the ShlExp, but as this one was created during optimize, it never happened. https://github.com/D-Programming-Language/dmd/pull/2528 -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
