| Summary | 0005354: Access Violation on Program Exit | ||||
| Description | I am getting an access violation on program exit when I use several different controls: TjvMemo, TjvEdit, TjvSimpleXML. I do NOT get an access violation with other controls, such as TjvEasterEgg. The program runs fine, but upon exiting, the access violation shows up. I have tried many version, from older versions of jcl and jvcl all the way up to the nightly builds. I have even reinstalled Codegear RAD Studio 2009 and reinstalled it, to no avail. I believe it has something to do with unicodestrings in some way. When the program crashes, the debugger takes me to the include <system> file and the section below: {$ELSE} // This is line 13860 asm { -> EAX pointer to str } MOV EDX,[EAX] { fetch str } TEST EDX,EDX { if nil, nothing to do } JE @@done MOV dword ptr [EAX],0 { clear str } MOV ECX,[EDX-skew].StrRec.refCnt { fetch refCnt } DEC ECX { if < 0: literal str } JL @@done // It always breaks at this line: LOCK DEC [EDX-skew].StrRec.refCnt { threadsafe dec refCount } JNE @@done PUSH EAX LEA EAX,[EDX-skew].StrRec.codePage { if refCnt now zero, deallocate} CALL _FreeMem POP EAX @@done: end; {$ENDIF} When I remove the “#pragma link “JvEdit” the av goes away. I have placed events “OnClose”, “OnCloseQuery”, “OnDestory” and in the destructor itself. OnClose and OnCloseQuery execute, then the AV occurs. Please let me know if more information is needed. | ||||
| Additional Information | This causes an access violation when the program closes. //--------------------------------------------------------------------------- #include <vcl.h> #pragma hdrstop #include "Unit3.h" //--------------------------------------------------------------------------- #pragma package(smart_init) #pragma link "JvEdit" #pragma link "JvExStdCtrls" #pragma resource "*.dfm" TForm3 *Form3; //--------------------------------------------------------------------------- __fastcall TForm3::TForm3(TComponent* Owner) : TForm(Owner) { } //--------------------------------------------------------------------------- This does not cause an access violation when the program closes because JvEdit is no longer linked. It has been commented out. #include <vcl.h> #pragma hdrstop #include "Unit3.h" //--------------------------------------------------------------------------- #pragma package(smart_init) //#pragma link "JvEdit" #pragma link "JvExStdCtrls" #pragma resource "*.dfm" TForm3 *Form3; //--------------------------------------------------------------------------- __fastcall TForm3::TForm3(TComponent* Owner) : TForm(Owner) { } //--------------------------------------------------------------------------- | ||||

BTW, I am running Windows XP SP3 with 2 Gig. I have tried everything I can think of in the way of options. Using dynamic runtime, not using dynamic runtime. Compile with/without packages. Installing JVCL with and without dxgettext support, etc. I also downloaded and installed gnu gettext for windows. |

|
What version of Delphi/C++ are you using? |
|
|
I'm using Codegear RAD Studio 2009. It builds it from the D12 packages. |
|
|
By "IT" I mean the Installer, BTW. |
|
|
I have the same problem. In 3.39 all run well, in 3.40 AV jn exit. |
|
|
Please try with the latest SVN content, I believe this was fixed in the JCL |
|
|
No news, I'm assuming this is fixed |
