RE: [boost] Re: [prereview request][fsm]
Hmm.. (spent some hours doing some more digging on this). I write a managed app, yet my dtor is called.. ok, so this is not a question for boost. I have not been able able to find anything in the MS docs as to "why" RAII is working managed, this goes against everything I have heard\understood.

For a managed class your dtor is called when the object is garbage collected, since that is when it is destroyed. For an unmanaged class it is the normal case of the dtor being called immediately whenever the object is destroyed, either through a delete in dynamic memory or the object going out of scope in non-dynamic memory. There is nothing mysterious about this in .NET. The difference is that garbage collection is not deterministic destruction, and mya run at any time.

This is all completely OT for Boost. Please take it to an appropriate forum. Thanks, -- Dave Abrahams Boost Moderator
