Delphi IDE - Access violation in module 'rtl70.bpl'
18,825
Solution 1
I have found the problem: In one control I was freeing (on Destroy) an object that was created something like this:
MyFoultyControl:= Create(AOwner);
MyFoultyControl.Parent:= ACowner;
Solution 2
Do you have CnPack installed ? Or another Delphi IDE enhancer ?
My problems started when I installed CnPack (otherwise a great product - woulnd't work without it).
When the error is received the editor part becomes read only (right click the editor to verify this in the popup menu).

Congrats Embarcadero! https://stackoverflow.blog/2017/10/31/disliked-programming-languages/ Why Borland failed? The Borland Turbo languages where the Cat's Pajamas. Microsoft countered with the Quick languages. Borland made Turbo Pascal for Windows and with Objects and then made Delphi. Microsoft countered with Visual BASIC. Borland made Borland C++ and JBuilder. Microsoft countered with Visual C++ and Visual J++/J# and then later Visual C#. The free IDEs and Free compiler languages ate into Borland's sales. Eclipse, Netbeans, IntelliJ, BlueJ, Sublime Text, GNU C/C++, Apple XCode, FreePascal/Lazarus, Ruby/Ruby on Rails, Python, Code::Blocks, etc. In 2005 Microsoft introduce Visual Studio Express a free version of their development tools. Like Amiga, Borland had the superior technology, but cheaper/free alternatives undercut their sales. Mostly, it was the free and open source revolution that did Borland in. orionblastar

I have and old AV that hunts me. It appears randomly (often but not always) when I switch between projects (close current project and double click a different DPR file to load it) or when I close Delphi (7). So it appears daily but not that offten and I can live with it. However, in the last few days it started to be really annoying.
Any idea where I could start? Here is the log for this AV:

Can anybody make any sense from the Call Stack section. Usually it points to the exact location of the problem, but now it doesn't really tell anything concrete.
Edit: I uninstalled ALL (and I really mean ALL) experts and external programs from IDE and I still have the AV. Now it appears in a different context, more exactly when I move the mouse above a variable and the tooltip (code insight) pops up.
