Urgent!! /O2 is behavior wrong,My code problem or Microsofts??????????

[john]

Hi,Gurus:
I got a ATL COM+ component (VC++ 2003 7.1), inside IDL Method1 (COM
Method), I call another Class Method2 (C++ class), the Method2 throw a
custom excetption
throw CBusError (_T("Custom"),_T("1407"));

in Method1
try {
...
Class1.Method2()
}
catch(CErrorBase& e)
{
}
catch(...)
{
}

when compile with /O2 (Release Mode), I got a unexpected error, the error
only by catch(...), not by CErrorBase
but when compiled with /O1 (Release Mode) or in debug mode, it work as
expected the error caught by CErrorBase

also in Method2, I have
std::string strMessageCode = "1234";
std::string strMessageSeverity = "323";
cstring cx1=("LA1748");
if ((strMessageCode== cx1))
throw CBusError(_T("ALLTEL"),_T("LA1407"));
else
throw CBusError (_T("ALLTEL"),_T("LA1407"));

but if I change
if ((strMessageCode== cx1)) to
if (1==2)
it work as expected even under /O2 (Release Mode)

so what is my problem?
Memory Corruption????
O2 Bug in VC++????
please advice.

Thanks in advance.
