SUMMARY
The /Oa (Assume No Aliasing) and /Ow (Assume Aliasing
Across Function Calls) options do not work correctly in the compiler shipped
with Visual C++ version 4.2b for Alpha. The same options can be selected via
the #pragma optimize statement.
If your code is compiled with the /Oa
or /Ow command-line options, or if the code you compile turns on the "a" or "w"
options in a #pragma optimize statement, your code could experience aliasing
problems. These problems most frequently manifest as corrupted data.
Version 10.20.7032 of c2.exe disables these options regardless of whether they
are set on the command line or using pragmas in the code.
