Const Char_t* changes

ROOT
1

Hi,

I’m compiling code with AClic inside ROOT CINT.
I have one function like this:

Int_t do_something(const Char_t* name1, const Char_t* name2) {
   TCollection::StartGarbageCollection();
   cout << "Before: " << endl;
   cout << name1 << endl;
   cout << name2 << endl;
   TFile* f1 = new TFile(name1);
   cout << "After: " << endl;
   cout << name1 << endl;
   cout << name2 << endl;

   // do stuff here
   return 0;
}

And another function that calls the first one:

Int_t do_it() {
   const Char_t* name1 = "f1.root";
   const Char_t* name2 = "f2.root";
   do_something(name1, name2);
   return 0;
}

After compiling, when I run do_it() at the interpreter prompt I get:

Before:
f1.root
f2.root
After:
f1.root
f1.root

I’ve worked around this using TStrings in function do_it(), like this:

Int_t do_it() {
   TString n1("f1.root");
   TString n2("f2.root");
   do_something(n1.Data(), n2.Data());
   return 0;
}
And now the output seems ok, but I think there's something seriously wrong with this behaviour... though I don't understand what has gone wrong with the char ponters...

Thank you for your attention, best regards,

  Rui

I cannot reproduce this problem with or without ACLIC
