GExperts is always compiled with the latest update of any of the supported Delphi versions. That unfortunately means that it may not work if the IDE hasn’t been updated to the latest version. E.g. The latest GExperts release will not work with Delphi 10.2, but only with Delphi 10.2.3, the latest update to Delphi 10.2. This is due to changes in the runtime packages that are not always backward compatible. Until a few years ago, this was no problem because when you bought Delphi you were automatically entitled to receive all updates for this version. E.g. if you bought Delphi 2007 you could download all updates for it and GExperts would simply work for you. This changed when Embarcadero tried to force all their customers to buy a maintenance subscription. Read on in the blog post.

Spot on! Thanks for letting me know I'm not completely insane yet. 😅

I gave DebugEngine a try and it is very good. Sometimes it provides stack traces strange (method where exception happened, two inner methods of DebugEngine and then the real stack trace) but it's really easy to install and use. It is also unaffected by the two issues I have with MadExcept (TThread.FatalException and Exception.InnerException is rendered useless). It comes with a utility to attach the map (or it's own compressed smap) format to the .EXE itself, however the final executable is larger than with MadExcept (guess the .map compression is not that advanced in DebugEngine than in MadExcept). I don't have much experience with JclDebug... I tried it once, and I disliked every bit of it. Only to be able to see stack traces I had to include ~30 extra files in my project and the stack traces were not accurate.; so I gave up on it. If you can fit into the free usage conditions of MadExcept I'd say go with that. Otherwise, DebugEngine (or a license for MadExcept) would be my choice. P.s.: keep in mind that also MadExcept and DebugEngine is known to have stack issues if the .exe is packed with UPX.
