Line 25 happens because of `[a.name]`. You request a new
array: the memory for this has to be allocated (the reason
why the compiler says "may" is because sometimes, e.g. if the
array literal itself contains only literals, the allocations
needn't happen at runtime and no GC call is necessary). Since
you don't actually use the array, get rid of it:

Hi,
Thank you for your help and the DMD version that i am using
is DMD 2.076.0 and yes I am on windows.
Please post a compilable, minimal example including how that
function gets called that yields you that compiler output.
Hi,
Please find the example code below,
import std.stdio: File,writeln;
import std.datetime.systime: Clock, days, SysTime;
import std.file: SpanMode, dirEntries, exists, isFile, mkdir,
remove;
import std.typecons: tuple;
import std.algorithm: filter, map, each;
import std.array: array;
void logClean (string[] Lglst, int LogAge) {
if (!Lglst[0].exists) { mkdir(Lglst[0]); }
auto ct1 = Clock.currTime();
auto st1 = ct1 + days(-LogAge);
auto dFiles = dirEntries(Lglst[0], SpanMode.shallow).filter!(a
=> a.exists && a.isFile && a.timeCreated < st1).map!(a =>
tuple(a.name)).array;
dFiles.each!(a => a[0].remove);
}
void main () {
string[] LogDir =
["C:\\Users\\bheev1\\Desktop\\Current\\Script\\D\\Logs"];
int LogAge = 1;
logClean(LogDir,LogAge);
}
Another similar issue :
I removed the [a.name] and the issue in line 25 has resolved,
but for another function i am getting the same error
string[][] cleanFiles(string FFs, string Step) {
auto dFiles = dirEntries(FFs, SpanMode.shallow).filter!(a =>
a.isFile).map!(a =>[a.name , a.timeCreated.toSimpleString[0 ..
20]]).array; -> Issue in this line
if (Step == "run")
dFiles.each!(a => a[0].remove);
return dFiles;
}
if the replace the line in error as below then i am getting the
error "Error: cannot implicitly convert expression dFiles of type
Tuple!(string, string)[] to string[][]"
auto dFiles = dirEntries(FFs, SpanMode.shallow).filter!(a =>
a.isFile).map!(a => tuple(a.name, a.timeCreated.toSimpleString[0
.. 20])).array;
