Description
Dear experts,
The ATLAS analysis frameworks often times exhibit a strange behavior that I was able to trace down to plain ROOT cling.
Please consider the following script:
#include "TROOT.h"
|
#include "TString.h"
|
|
|
#include <iostream>
|
|
|
int main(){ |
|
|
TString str = "kRed"; |
int val = kRed; |
|
|
for(size_t i=0; i<100000; i++){ |
int valx = gROOT->ProcessLine(str+";"); |
if (val != valx){ |
std::cout << "oups!" << std::endl; |
exit(1); |
} else { |
std::cout << "."; |
}
|
}
|
std::cout << std::endl;
|
return 0; |
}
|
The first couple of thousand iterations run fine, but after several ten thousand calls to the interpreter, warnings of the following type start to appear:
In file included from input_line_6:{somenumber}:
|
In file included from {/path/to/some/header/file}
|
input_line_{somenumber}:2:2: warning: expression result unused [-Wunused-value] |
This does not affect the results of the code, but makes any log file or output stream highly unintelligible. Is it possible to somehow suppress these messages entirely?
