Question: Sometimes, when i have saved GUID* of track somewhere => then i delete that track => GUID* now points to restricted area with unknown data => trying to get access it (e.g. for comparing or guidtostring func) crashes REAPER (acces violation), what do you do in such cases, how do you check is GUID is still valid without crashing?

    Don't save the GUID pointer, copy the value out instead.

    Then it's probably will be slow, if i need to save/remove/process a lot of manipulations with tracks. But if it's the only option, ok ,thanks.

    Copying the value is copying 16 bytes of memory, which is basically free.

    For some reason i thought it's 64 bytes, just checked right now and it's 16, stupid me. I'll do as You say. I realize i need to redo thousands of code, haha... oh,no...

    Even 64 bytes is pretty small and fast, if you manage your allocations right. If you have 1000 tracks that's 64kb, which is TINY. :)
