https://issues.dlang.org/show_bug.cgi?id=23279 Issue ID: 23279 Summary: Segmentation fault on mixin template + using unknown type Product: D Version: D2 Hardware: x86 OS: Windows Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: msnmancini hotmail.com This is an example code of what is causing a segmentation fault: ```d template getParams (alias fn) { static if ( is(typeof(fn) params == __parameters) ) alias getParams = params; } template hasMethod(T, string method, Params...) { enum hasMethod = __traits(hasMember, T, method) && is(getParams!(__traits(getMember, T, method)) == Params); } mixin template TestMx() { static if(hasMethod!( typeof(this), "setIt", Tester)){} } class Tester { mixin TestMx; void setIt(Sth sth){} } ``` I don't know (or didn't test) on how to further reduce that, but it seems small enough. The error occurs when the mixin TestMx is called. --
