[minicoredumper] Invalid stack when all memory regions are dumped

[Abhi Arjun]

Im the recept file, under maps section if only "[vdso]" is present  then I get proper stack in gdb. However if I add "*" to include all memory regions (that's my requirement), then stack becomes invalid/corrupted as shown below.  I just have main() function in the program. 

Am I missing something? Please let me know.
Included further details below. 
Regards,
Abhi
