Segmentation Fault due to Erase (Vector)

When I try to use the erase function within vector to erase a 'list', I get a segmentation fault. I am using clang++, c++11. The line of code I am struggling with is:

studentEntries.erase(std::find(studentEntries.begin(), studentEntries.end(), it));

studentEntries is a vector of lists of strings. ie:

std::vector<std::list<std::string>> studentEntries;

If more context would be helpful I also uploaded my project to pastebin (57 lines total). The problem is on line 27.
