Close the RAD Studio IDE<p>2. Backup existing files<p> The patch replaces files in the install location (likely C:\Program files (x86)\Embarcadero\Studio\20.0, referred to as <install-root>) and subfolders. A file list is included at the end of this document.<br> a. Back up all files listed, or,<br> b. Back up the source\cpprtl, include\windows\crtl, include\dinkumware64, bin, bin64, lib\win32, lib\win32c, lib\win64 folders<p>3. Extract the zip file to a temporary directory<p>4. Copy the files to the <install-root> folder, overwriting the files you previously backed up<p>You can now restart RAD Studio.<p>This does not include localized versions of the compiler. After you apply this hotfix, all compiler warning and error messages will be in English. Do not change the RAD Studio langage after applying this hotfix. If you do, please re-apply the hotfix.<p>Fix list<p>This patch fixes the following publicly reported issues:<ul><li>RSP-21824 Clang: __finally block contains corrupt class members and local objects</li><li>RSP-21704 Compiler version predefined macros are not updated</li><li>RSP-21658 ilink32: Unresolved external 'operator new(unsigned int, std::align_val_t)' and 'operator delete(void *, std::align_val_t)'</li><li>RSP-21657 bcc32c parallel compilation fails to work!</li><li>RSP-21653 System.ZLib fails to link for Win64</li><li>RSP-21612 bcc32c erroneously gives sizeof(long double) as 10, but reserves 12 bytes</li><li>RSP-21609 Memory display unable to show padded extended from bcc32c</li><li>RSP-22339 Problem with Ansi character constant encoding</li><li>RSP-20552 chrono::steady_clock is chrono::system_clock which is not steady</li><li>RSP-18752 std::chrono::steady_clock::now() returns time_point<system_clock> instead of time_point<steady_clock></li></ul>There were also some internally reported issues.<p>File list<p>bin\bcc32c.exe<br>bin\bcc32x.exe<br>bin\bcc64.exe<br>bin\bccaarm.exe<br>bin\bcciosarm.exe<br>bin\bcciosarm64.exe<br>bin\cc32260.dll<br>bin\cc32260mt.dll<br>bin\cc32c260.dll<br>bin\cc32c260mt.dll<br>bin\compclang33.dll<br>bin\compclang33.jdbg<br>bin\compclang50.dll<br>bin\compclang50.jdbg<br>bin64\cc64260.dll<br>bin64\cc64260mt.dll<br>include\dinkumware64\chrono<br>include\dinkumware64\new<br>include\dinkumware64\xtimec.h<br>include\windows\crtl\time.h<br>lib\win32\release\cp32mt.lib<br>lib\win32\release\cp32mti.lib<br>lib\win32\release\cw32.lib<br>lib\win32\release\cw32i.lib<br>lib\win32\release\cw32mt.lib<br>lib\win32\release\cw32mti.lib<br>lib\win32c\debug\cp32mt.lib<br>lib\win32c\debug\cp32mti.lib<br>lib\win32c\debug\cw32.lib<br>lib\win32c\debug\cw32i.lib<br>lib\win32c\debug\cw32mt.lib<br>lib\win32c\debug\cw32mti.lib<br>lib\win32c\release\cp32mt.lib<br>lib\win32c\release\cp32mti.lib<br>lib\win32c\release\cw32.lib<br>lib\win32c\release\cw32i.lib<br>lib\win32c\release\cw32mt.lib<br>lib\win32c\release\cw32mti.lib<br>lib\win64\debug\cp64mt.a<br>lib\win64\debug\cp64mti.a<br>lib\win64\debug\cw64.a<br>lib\win64\debug\cw64i.a<br>lib\win64\debug\cw64mt.a<br>lib\win64\release\cp64mt.a<br>lib\win64\release\cp64mti.a<br>lib\win64\release\cw64.a<br>lib\win64\release\cw64i.a<br>lib\win64\release\cw64mt.a<br>source\cpprtl\Source\dinkumware64\source\Dinkum\xtime.c<br>source\cpprtl\Source\io\io_stub64.c<br>source\cpprtl\Source\io\makefile<br><p>Available only to registered users of Delphi, C++Builder, RAD Studio 10.3, and Embarcadero All-Access XE<p>English, French, German and Japanese<p>MD5: ED466D75CE1D486E17EB76A8B398C5D3
