My program crashes and a dialog box shows

"Unhandled exception at 0x3aaf1aea (pmsqlsrv.dll) in java.exe: 0xC0000005:
Access violation reading location 0x3ac60880."

The statement shown as causing the crash is
m_pDatabase->m_pIDBCreateCommand->CreateCommand();

In the watch window,
"this" pointer value for the containing object is 0x7395fcaf
m_pDatabase is 0xffff8810 (does it look like a valid address?)
m_pDatabase->m_pIDBCreateCommand CXX0030: Error: expression cannot be evaluated

The addresses shown in the crash dialog box - 0xC0000005 and 0x3ac60880 I don't know what they are. Does this mean that the dll (pmsqlsrv.dll) itself is corrupted and the crash is in reading the code segment rather than in accessing the data?

Please help before I shoot myself.
