Did you try to debug memory leaks?

I do have such main

GUI_APP_MAIN
{
#ifdef _DEBUG
	StdLogSetup(LOG_COUT|LOG_FILE);
	HttpRequest::Trace();
#endif

    MyAppWindow().Run();
}

and getting such LOG (under spoiler)

****************** PANIC: Memory leaks detected! (final check)

but didn't know what to do with it Embarassed

- taking into consideration this part:
Quote:

Of course, the only problem with this is that the order of allocations must be exactly the same in the "test run". Which is often not, but usually it is possible to arrange it so after spending a couple of nights desperately looking for the source of leak in the code using other methods...

... while using ONLY U++ & neither VisualStudio tools nor Deleaker for Qt - it was problematic for me to deal with this LOG's info... therefore I have only debugger in my disposal & its FreeFreeFree_etc in one variable & my supposition that it concerns the leak?.. by the way original code, though not leaking is in examples in u++ (as in my screen was) & when using it not in main, but in secondary thread - I'm getting memory leaks (as I already mentioned)... therefore I supposed that httpRequest can give memory leak, but in ST-app these leaks are being hidden somehow, though in MT-app are being revealed by assertion... IMHO... if async loading takes place in secondary thread... BTW it's not a Server, just some requests to some html_pages (multiple)...

visit this site tomorrow and all new information should be there.

ok - will wait till tomorrow - thank you!

Alternatively you could update to the latest SVN version and read new documentation page inside TheIDE

I do not see any updater in the ide itself... is it possible only from the git? - I am not connected to it anyway...
Klugier wrote on Sat, 31 October 2020 15:02

or just read the raw data in commit content available on GitHub (Click on Load Diff for obtaining content).

have got... thank you!
but my results you can see under spoiler in this message above here - until I'll find what to do with it from your paper... Rolling Eyes

because I don't know yet... and you are not telling about openSSL behavior in my situation described

Best regards.
