Can I have an array of boost::shared_ptr?

Hi, 

I have a problem with the code below. It uses boost::shared_ptr. It 
crashes on the assertion in main. I debugged it and it looks like
with 
C++Builder 5 (bcc32 version is 5.5) destructor for sp1_[ 0 ] is
called 
twice and for sp2_[ 0 ] never. When using gcc 2.95.2 no destructor is 
called even if the line #if 1 is changed to #if 0. It works fine with 
MSVC++ 6 SP3, though.

Can anyone suggest a workaround or explain to me what am I doing 
wrong?

I want to put boost::shared_ptr objects into an array which then will 
be used to initialize a STL container.

Thank you.
