Problems with list<string>.push_back

ROOT

Hello ROOTers,
I found a loss of the backward compatibility for v4.00.08.
My interpreted macro runs fine by the v4.00.06, while crashes, while running v4.00.08.

Error: Can’t call list<string,allocator >::push_back(s) in current scope FILE:tasks.C LINE:137
Possible candidates are…
filename line:size busy function type and name (in list<string,allocator >)
Error: Symbol lfiles1 is not defined in current scope FILE:tasks.C LINE:137
Error: Failed to evaluate lfiles1.push_back(s)Possible candidates are…
filename line:size busy function type and name
*** Interpreter error recovered ***

The break point is here:

list lfiles1;
string s = “treetestmc1.root”;
lfiles1.push_back(s); <=============

Unfortunately, the compiled version of the mentioned macro and a short test version
playing with a list runs OK.

If you are intrerested in the above problem let me know and i’ll send the files.

Hi,
I filtered the reason.
It is the line in one of the compiled implementation files(Collection.cxx):

typedef std::liststd::string::const_iterator ItLString;

that causes the crash.
I’ve prepared a small test(see att.).

                                                Regards, Valery.
