https://issues.dlang.org/show_bug.cgi?id=13030 Issue ID: 13030 Summary: DMD assertion fails at mtype.c:697 if delegate has an argument name Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: normal Priority: P1 Component: DMD Assignee: nobody puremagic.com Reporter: liran weka.io The following code: void va(Args...)(const Args args) {} void func(int delegate(int n) a) { va(a); } causes an assertion in dmd: dmd: mtype.c:697: void Type::fixTo(Type*): Assertion `mod != t->mod' failed. If the name of the delegate argument is removed [no 'n'] it compiles. If the called function has just a single template [void mva(T)(const T args)] it compiles. If the called functions receives non const args [void mva(A...)(A args)] it also compiles. This is the minimal set of lines that I was able to get to in order to recreate the assertion error. DMD64 D Compiler v2.065, fails on Linux and Mac OSX.(Did not try on other platforms) --
