Subject: Visual C++ and RUBY

Hi there!

I am again evaluating RUBY as an embedded scripting language for a large
C++ application which is developed using Microsoft VIsual C++ .NET 2003 
Beta 1 ( aka "Everet" ) its the successor to Visual Studio .NET or VC7.0
and has VC7.1 as its version tag as well as the MSVC compiler version 1310..

Ok back to my question. I am using RUBY 1.6.7 and everything works ok.. 
however someone pointed out to me that whenever an exception occurs in 
RUBY code RUBy executes a long jump ...and thus the stack gets not 
cleaned up ... in particular consider this example:

class SomeClass { .... }

void MyFunction()
{
   SomeClass localInstanceOnStack;
   CallSomeRubyMethod( "MyRubyMethod" );
}

Now when the call to the ruby method "MyRubyMethod" results in an 
exception, the "LocalInstanceOnStack" class var will never be 
deleted/the destructor not called.....

Is this true ? Or are the problems different with the longjmp "feature" ?

I need to clarify this, since i am embedding Ruby into a high available
server application so it needs to be stable.....

If this is true, is there any way around this, or any future changes 
that will solve this ?

Thanks in advance
