Hi,
Today I have just found a weird bug in std.logger. Consider:
```d
import std.logger : info;
void main() {
info(foo());
}
auto foo() {
info("In foo");
return "Hello, world.";
}
```
The output is:
```
2023-10-31T20:41:05.274 [info] onlineapp.d:8:foo In foo
2023-10-31T20:41:05.274 [info] onlineapp.d:8:foo In fooHello, world.
```
The second line is obviously wrong, as it repeats the first line as its
header. That's why I suspect memory corruption.
Assigning the value to a variable works as expected:
```d
import std.logger : info;
void main() {
auto s = foo();
info(s);
}
auto foo() {
info("In foo");
return "Hello, world.";
}
```
gets the proper output:
```
2023-10-31T21:09:46.529 [info] onlineapp.d:9:foo In foo
2023-10-31T21:09:46.529 [info] onlineapp.d:5:main Hello, world.
```
I can only imagine that it's related to the logging functions taking
lazy arguments, although I cannot see why it would be a problem in a
simple case like this.
