Issue ID: 21055
Summary: core.stdc.stdarg is not @nogc
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Keywords: betterC
Severity: normal
Priority: P1
Component: druntime
Assignee: nobody at puremagic.com
Reporter: dkorpel at live.nl
```
import core.stdc.stdarg;
import core.stdc.stdio;
extern(C) void foo(const(char)* format, ...) @nogc {
va_list vl;
va_start(vl, format);
vprintf(format, vl);
va_end(vl);
}
void main() {
foo("ten = %d", 10);
}
```
onlineapp.d(6): Error: @nogc function onlineapp.foo cannot call non- at nogc
function core.stdc.stdarg.va_start!(const(char)*).va_start
onlineapp.d(8): Error: @nogc function onlineapp.foo cannot call non- at nogc
function core.stdc.stdarg.va_end
This makes no sense, the C code does not need a GC so neither should D.
On top of core/stdc/stdarg.d it says:
//@nogc: // Not yet, need to make TypeInfo's member functions @nogc first
That was added when stdarg looked like this:
https://github.com/dlang/druntime/blob/8c07338efe375f8ba4b687c8e9085d4ba686963a/src/core/stdc/stdarg.d
Currently I see no trace of TypeInfo anymore.
