I once reported the same error for the 3.12.x versions, and I think it got fixed then. But today I again ended up on the same error.
The context:
- Windows 10, latest updates installed.
- Visual Studio 2019, latest version.
- Debug build and debug libs.
- Both LexActivator and LexFloatClient statically linked.
- Stand-alone windows application.
- The license was already activated in a previous session quite a few days ago, and no license update was performed since, and certainly not during the crashing session.
- All default LA functions got called directly at startup (SetProductData, SetProductId, SetAppVersion, IsLicenseGenuine, etc.).
- A license callback routine had been registered with SetLicenseCallback for the LA lib, but not for the LF lib, but it got nullptr’ed directly on the 1st callback. (no proof of this, but that’s just how this app works per definition, without exception, so I don’t expect anything else.)
- I closed the app with Alt-F4, but this time not split-second after opening it like in my previous 3.12.x bug reports; I must have had it open for quite a few minutes (though not for hours, i.e. not anything near the license server sync period).
- I did do some debugging work in the app, but nothing fancy (only some breakpoints and variable value checking, definitely not code recompile & resume or such).
I managed to catch the following callstack; I hope it helps you guys pinpoint it a bit…
