Re: [Flightgear-devel] try ... catch ... throw (up)
Here's what I'm doing:
In the Table class:
In FGTable constructor:
if (operation_types.find(parent_type) == string::npos) {
internal = true;
} else {
throw(string(An internal table cannot be ...));
}
Now, this seems to work OK - I throw an exception if a situation
occurs that is invalid.

I'm probably missing something fundamental here. Anyone have any suggestions?

I am unsure it is OK to through a temporary object like this.
It's created on the stack right there at the same frame where it's thrown,
but IIRC, as throw unwinds the stack, it is auto-destructed. You should
be throwing an object that has lifetime encompassing the outer catch
handler.
