Question
Can multiple instances of the same stack entity run on one processor ?
Answers
This depends upon the operating system.
In OS like Solaris, Windows NT etc., where each instance / execution of the stack entity has its own data area, this is possible. 
In RTOS like VxWorks etc., the global variables are mapped to a fixed location in memory (flat memory structure). Hence, multiple instances of the stack entity access the same data area for globals, leading to clash.    Your Comment
