How to create new c++ object in gdb prompt via new operator

Question

How to create c++ object via new operator in gdb.
I am looking for something similar to

option-1) (gdb) call new ClassType()
or
option-2) (gdb) set $obj = new ClassType()

But both of these options failing in gdb.

I am sorry, I should have mentioned both of above fail with error in gdb. — sunil, Feb 12 '22 at 19:28

Try this way:

set var $new = malloc(sizeof(class ClassType))
call ClassType::ClassType($var)
