AV in 64 bit application if using the debugger - JuergenS - 06-26-2024
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()()

:00007FF8B97D7344 BaseThreadInitThunk()
:00007FF8BB35CC91 RtlUserThreadStart()
The debug release is working well if i don't start the application with debugger !!!
Regards

It seems to me, that the INTRAWEB service dialog is causing the problem.
