Bug ID: 109108
Summary: d: Undefined reference to lambda in private enum
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: ibuclaw at gcc dot gnu.org
Target Milestone: ---
Similar to pr108055. Lambdas should be emitted in every module they are
referenced from.
```
import other;
void main()
{
auto a = callFun(1);
}
```
```
private enum int function(ref int)[] funs =
[
0: (ref idx) => 0,
1: (ref idx) => 1,
];
int callFun(I)(I idx)
{
return funs[idx](idx);
}
```
Only compiling the "main" module results in linker errors.
