Application crash in Windows 2003 Server SP2

[Rajavelu]

Hi,

There is a legacy application that runs fine from Win 98 SE up till Win 2003
Server. The application makes connectivity to an HTTPS URL. When the app is
to use proxy server for its connectivity, the application crashes in Win 2K3
SP2 Server and the same works for other operating systems (even in Win 2K3
Server without SP1 or SP2).

I could see the following in system's Application Log:

Faulting application XYZ.exe, version 4.5.2.0, faulting module ntdll.dll,
version 5.2.3790.1830, fault address 0x000224b2

There is also a Dr Watson log that succeeds above log and has the following;

The application, C:\ABC\XYZ.exe, generated an application error The error
occurred on 08/15/2008 @ 15:23:16.509 The exception generated was c0000005 at
address 7C8224B2 (ntdll!ExpInterlockedPopEntrySListFault)


Is there any way to diagnaise the cause ? Is there any known workaround ?

Thanks much for your time.
