If you use VCL grids or C++Builder, we recommend you install Patch #3, which we released today. This patch addresses a number of issues in RAD Studio 10.4 for the VCL Grid, the C++ Win64 debugger (including adding a new formatter), C++ Builder Android exceptions, and C++ Android resource linking.

RAD Studio 10.4 Patch #3 addresses the following both customer-reported (RSP-) and internal (RS-) issues:

C++ Android: RSP-27268 C++ Builder 10.3.3 Android Exceptions RSP-29218 C++ Android error E4620 processing resource .fmx -2 raised

VCL: RSP-29628 VCL Grids bug

C++ Win64 Debugging: RSP-29239 Debugger does not start RSP-29206 can't debug win64 at all RSP-29145 C++Builder 64 bit Debugger alters the default working directory from the app executable directory RSP-29125 New Windows 64 bit debugger freezes and does not stop on exceptions

  • Partial fix: Exception handling support in the debugger has been improved but there are still issues: OS-level exceptions (e.g. AV) are not always caught and reported. Some language-level exception types are not displayed correctly RS-100553 [LLDB Win64 C++] Add formatter for unique_ptr RS-100134 FMX & VCL C++ 64-bit App become unresponsive while trying to debug it RS-97111 Evaluation of TLabel->Caption property returns "Unknown error"

This is an important set of fixes. As well as the VCL grids issue, which affects you if you use this control, it's notable for the C++ items. First, Android exception handling is important if you ran into this issue and need to update your Android 32-bit app by the August 1st deadline. The resource linking issue is also worthwhile. Second, when 10.4 was released we added a new debugger for Win64, which is a huge improvement: it's based on LLDB 9, has tools to evaluate and inspect STL collections or your own complex data structures, and more - it's now on par with the classic debugger, which is important for moving to Clang. This patch fixes a number of bugs, especially with large projects, and also adds a new formatter (visualiser) for std::unique_ptr so you can easily inspect their contents.
