Well, i tried your sample program in my macbook pro. In my mbp everything works
fine but not in the iMac. Here is the callstack of the well-behaved execution
(I added a breakpoint int ~Object()):
Code:

In my macbook pro I built OSG using gcc version 4.2.1 (Based on Apple Inc.
build 5658) (LLVM build 2336.9.00):
Using built-in specs.
Target: i686-apple-darwin11
Configured with: /private/var/tmp/llvmgcc42/llvmgcc42-2336.9~22/src/configure
--disable-checking --enable-werror
--prefix=/Applications/Xcode.app/Contents/Developer/usr/llvm-gcc-4.2
--mandir=/share/man --enable-languages=c,objc,c++,obj-c++
--program-prefix=llvm- --program-transform-name=/^[cg][^.-]*$/s/$/-4.2/
--with-slibdir=/usr/lib --build=i686-apple-darwin11
--enable-llvm=/private/var/tmp/llvmgcc42/llvmgcc42-2336.9~22/dst-llvmCore/Developer/usr/local
--program-prefix=i686-apple-darwin11- --host=x86_64-apple-darwin11
--target=i686-apple-darwin11 --with-gxx-include-dir=/usr/include/c++/4.2.1
Thread model: posix
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00)
Curiously, I've the same configuration on the iMac and in it it doesn't work.
In the next post i will show the callstack when it fails. In advance, I will
say you that is different if i build using gcc instead of using clang.
