AV in 64 bit application if using the debugger

[JuergenS]

Hi, i could use some help

C++Builder 12.1
INTRAWEB 15.6.2

I have migrated an INTRAWEB application to 64 bit.

If i start the application with debugger the INTRAWEB debug dialog is shown and i can choose a browser to start.

The website is shown but after some action the following exception message is shown in a message box:

Erste Gelegenheit für Exception bei $0000000001A5C1DC.
Exception-Klasse 0xc0000005 mit Meldung 'Exception 0xc0000005 encountered at address 0x1a5c1dc: Access violation reading location 0xffffffffffffffff'.
Prozess XXX.exe (5740)

Nothing happens anymore in the browser window, the server is locked an needs to be terminated.


Call stack:

:0000000001A5C1DC Inthread::TInThreadWithTask::SetTask(Intask::TInTask*)()
:0000000001A5B134 Inschedulerofthread::TInSchedulerOfThread::StartYarn(Inyarn::TInYarn*, Intask::TInTask*)()
:0000000001A5AFCE Incustomtcpserver::TIdListenerThread::Run()()
:0000000001A5B6AB Inthread::TInThread::Execute()()
:0000000001893203 System::Classes::ThreadProc(System::Classes::TThread*)()
:00000000017EE2BD System::ThreadWrapper(void*)()
:00007FF8B97D7344 BaseThreadInitThunk()
:00007FF8BB35CC91 RtlUserThreadStart()

The debug release is working well if i don't start the application with debugger !!!
