Getting error while using OpenMP along with map in c++

[doijadss]

I am using map for assigning an identifiers for a line from file in c++.
also i am using IDs for a pattern in line {name,operator, val} which is separated by ';'.
I am using read_pub() for calculating how many patterns are there in a line.

What is the problem in this code.?

When I look up your error (*** glibc detected *** ./a.out: double free or corruption (fasttop): 0x00007f4458000 920 ***) I get the impression that some how either you freed the same thing twice or you corrupted its data structures, perhaps by over running a buffer.

Sorry, I'm not able to dig thru some 150+ lines of code right now to determine which or what; however, hopfully this will get you on the correct path to debuging your code.
