Delphi/RAD Studio debugger unusable => Fixed in SVN

[Serge Kraikov]

After updating from 4.2.18 to 4.3 the built-in debugger on RAD Studio does not step over/step into, it stays on the breakpoint line constantly.

I reproduced this issue in 4.3.2, 4.3.4 and in the latest 4.3.6 (these are the all 4.3.x versions I tested).

I encountered this issue on all XE, XE2, XE3, XE4 and XE5 versions of the RAD Studio (other users encountered this issue on Delphi7 also). There is a free trial version of affected RAD Studio XE5 on embarcadero.com site.

I run ArchLinux x64.

After downgrading to 4.2.18 this issue disappears.

Note there was issue with Visual Studio debugger #9659 that did not work in 4.2 versions but it was fixed in 4.3.

[DeveloperDave]

Still an issue as at 4.3.8.r92456 - affects my Delphi 5, 7, XE5

[Ramshankar Venkataraman]

There were some fixes to pending debug exceptions, stepping over IO instructions on Intel VT-x which didn't make it into 4.3.8.

Could you please if the following 4.3.9 test build helps the problem?

Windows host

Linux (64-bit) host

(Links expire in ~14 days).

[Ramshankar Venkataraman]

So does it fix the problem you have?

[DeveloperDave]

Yes. Fixed. (as noted in the VM / Delphi versions I have above)

[Ramshankar Venkataraman]

Thanks for testing, the fix will be available in the next maintenance release (4.3.10).

Experiencing the same problem after upgrading to test build 4.3.9 r92672.

I'm running Windows 7 on host and guest. Version of RAD Studio is Delphi 2010.

[Ramshankar Venkataraman]

The other reporter claims Delphi 2009 works. Is this Delphi 2010 RAD Studio free to download and test?

It would save time if I can get a direct download link as well as a testcase to try out.

[ksc654]

Unfortunately no. Only the most recent version is available as a trial. For now I've downgraded to 4.2.22.

[Frank Mehnert]

Fix is part of VBox 4.3.10.

[Serge Kraikov]

I confirm this issue is fixed in v4.3.10, thank you.
Tested ArchLinux x64 host with Windows 7 x86 guests and RAD Studio XE5 and XE4.

[Frank Mehnert]

ksc654, still this problem with VBox 4.3.12? In that case, please reopen and add a new VBox.log file with VBox 4.3.12.

[gvm]

In VirtualBox 6.x, this problem appeared again ...

[aeichner]

No follow up by the user reopening the ticket and no VBox.log provided, closing. Please reopen if still an issue with the most recent VirtualBox release and provide at least a VBox.log of the affected VM and a detailed description of the steps you are taking to reproduce this.
