glibc detected *** ./index: free(): invalid pointer

[dragoonts]

Hello everyone,

I was making a relatively simple program to index a .txt file for class, and I got the following error trying to run it.
*** glibc detected *** ./index: free(): invalid pointer: 0x000000000060b600 ***

I'm unsure of what could be causing the problem. I am primarily using vectors and a struct (with a string, int and array as fields). I'd rather not post the source just because it has to deal with school, but if someone would like to help me 1-on-1, I would gladly show them.

Thank you very much.

I compiled using g++ and a makefile (both are standard in the course I am taking, and the makefile was given to us by our prof, so it is correctly built).

Are you using delete somewhere? Make sure the pointer is valid and that it was actually created with new.

I am not using delete anywhere in my code, neither am I creating pointers explicitly.
Essentially, my code works like:
-Read line of .txt doc, remove punctuation, separate words (working fine)
-Create a word object for each word
-For each word, check if it's already in the vector. If yes, update the fields(occurences and pages array), if no, insert it so the vector remains alphabetically sorted.
-Print the words, their occurrences, and the pages they occur to another .txt file



EDIT: I just fixed it. There was an error in a for loop, simple as that.
