Watch global variables randomly show up zeroed out

Hi! Thanks for your work on this great debugger. Unfortunately, a certain issue started happening recently which prevents me from using it entirely, namely global variables appear zeroed out.

I've tried switching a bunch of compiler and linker flags on and off but the issue persists. There's the red background on some watched variables but no indication to help me diagnose further. This is specific to the RAD debugger, as Visual Studio does not have any issues viewing values for these variables.

I don't have steps to reproduce, but I think some indication of why a value appears in red would be helpful.

Perhaps there's something on my end that I could do to extract the error that prevents globals from showing?
