Found BUG of compiler VC++.NET 7.0 ?

[Alek]

Environment:
VS.NET 7.0
VC++

- Application multithread (imported from VS6.0 version)
- compiling in ReleaseMinDependency

My application creahsed only in deploy machine so I inserted trace point to understand where was mistake.
So I see that if I compile application in debug mode trace point logged correct information. Instead if I compile in ReleaseMinDependency trace point refer other point of code differente from where exception was raised !!
the code:

******************************************
................

sm.insert(SicMap::value_type(string(tCode), string(tDescr)));

tracePoint = 21;

ssic.insert(tCode);

tracePoint = 22;

...........

tracePoint = 23;

pri = NULL; //--> so I force exception on next line

TCHAR *tRow = new TCHAR[pri->sici.OutputSICSize];

...............
catch (...)

{

char msg[500];

sprintf(msg, " - Error ProcessSIC - tracePoint = %d", tracePoint);

spLog->Write(CComBSTR(msg));

throw;

}

***********************************

So, only in ReleaseMinDependency system log tracePoint = 21 instead of 23

And the cause seems the compiler optimization:

- disabled (Debug) -> /Od -> log is ok

- Maximize speed (ReleaseMinDependency) -> /O2 -> log is not ok

may be a bug of compiler ?

thanks a lot

bye
