QString::toStdString memory leak

[mshehata]

Hi All, I am using the member function "toStdString" of QString class to convert QString to std string. Conversion is done correctly but I ran memcheck tool of valgrind to check the memory and I found that there are a lot of leaks existing due to the conversion using "toStdString".
Is it a known issue? and if yes, Is there a way to avoid using it and perform the same conversion?

Hi, welcome to devnet

I just checked this on Windows with "VLD":https://vld.codeplex.com/ and can't confirm this.
Can you show an example of code that seems to leak?

I've just coded this lines and valgrind didn't find any memory leak.

@
#include <QString>
#include <iostream>

int main(int argc, char *argv[])
{
QString qstring("test");

    std::cout << qstring.toStdString() << std::endl;

    return 0;

}

Ok, many thanks Chris and tarod.net for your efforts.
It seems to be a false detection.
