https://issues.dlang.org/show_bug.cgi?id=21477 Issue ID: 21477 Summary: TypeInfo errors in betterC are cryptic Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: dave287091 gmail.com A minimal program, compiled with -betterC: extern(C) int main(){ int[] foo = [1]; return 0; } Yields the error message: bug.d(2): Error: TypeInfo cannot be used with -betterC It is correct to error, but the error is hard to understand. It would be much nicer nice if the error reported what it was trying to generate type info for (the usage that forces generation of type info can be very far from the declaration) and why TypeInfo was being generated in this case. Also, it is not clear to me that this is even the right error message. Why is it complaining about TypeInfo when the real issue is you can’t use runtime-managed dynamic arrays in betterC? --
