This question would be more appropriate for a general C language
mailing list.  The mailing list gcc@gcc.gnu.org is for people working
on developing the gcc compiler.

Please direct any followups elsewhere.  Thanks.

Yes, allocating objects on the stack is faster.  Deleting them is also
faster.  The performance differences are not negligible.  I don't know
of any papers; it's just obvious if you look at the generated code.
