Lotus C++ API toolkit code crashes on "delete LNNoteArray" on windows server 2008 R2 64 bit

Question

I upgraded our OS to Windows server 2008 R2 64 bit recently. I was using C/C++ API toolkit 8.0 version (with Lotus Notes client 8.5).

All the sample exe's (32 bit version) ran fine on that machine in emulation mode.

For one sample code i made some changes, i.e instead of doing - LNNoteArray SearchSet

I did - LNNoteArray* pSearchSet = new LNNoteArray();

and later- delete pSearchSet;

This crashes on "delete pSearchSet" on windows server 2008 r2, 64 bit.

Works fine on windows server 2k3, 32 bit. The sample code is ftsearch.cpp

Does anyone have any idea about this issue??
