The ansi-alias checker is disabled unless option -ansi-alias-check or /Qansi-alias-check has been specified.

Description

This option enables or disables the ansi-alias checker. The ansi-alias checker checks the source code for potential violations of ANSI aliasing rules and disables unsafe optimizations related to the code for those statements that are identified as potential violations.

You can use option –Wstrict-aliasing to identify potential violations.

If the [Q]ansi-alias option has been specified, the ansi-alias checker is enabled by default. You can use the negative form of the option (see Syntax above) to disable the checker.
