Using closure causes GC allocation

[Vino.B via Digitalmars-d-learn]

Hi All,

   Request your help on how to solve the issue in the below code 
as when i execute the program with -vgc it state as below:

NewTD.d(21): vgc: using closure causes GC allocation
NewTD.d(25): vgc: array literal may cause GC allocation

void logClean (string[] Lglst, int LogAge) {   //Line 21
        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 
=>[a.name]).array;  // Line 25
          dFiles.each!(f => f[0].remove);
}

From,
