[aspectc-user] pointcut on new and delete operator

[Olaf Spinczyk]

Hi,

the problem with your example is that execution advice only affects 
functions that are *defined* in a file that belongs to your project. It 
never affects builtin functions such as the builtin new and delete 
operators. If you would define a new class with a new/delete operator or 
(as a possible workaround) you own global new/delete operator, your 
advice would match.

There is a plan to support *call* advice on builtin functions, but I 
don't know when this feature will be integrated.

Best regards,

Olaf
