*** glib detected *** vectors

[CptSJP]

Hi I'm writing a program that takes a randomly generated vector and checks that vector to see if there are any repeated elements. If there are, I am to delete those elements.I can't declare any new vectors, I can't change the order of any non repeated numbers and I can only use the vector functions pop_back(), push_back(), and .size().

ex.
vector generated by program: 3 5 1 1 4 2 4 1 3 5

vector after it goes through the program: 3 5 1 4 2

my program compiles (using g++ -ansi - pedantic -Wconversion) and it runs and outputs everything it supposed to but it prints out a whole block of text starting with
"*** glib detected ***. What does this mean?


here is the part of my code where I think I went wrong if you need it.
Thank you for taking the time to read this


int holder = 0;
for(int i = 0; i < static_cast<int>(hasRepeats.size());i = i + 1)
{
for(int j = static_cast<int>(hasRepeats.size()) - 1; j >= 0; j = j - 1)
{
if(j != i)
{
if(hasRepeats[i] == hasRepeats[j] && j == static_cast<int>(hasRepeats.size()) - 1)
{
hasRepeats.pop_back();
}
else if(hasRepeats[i] == hasRepeats[j] && j != static_cast<int>(hasRepeats.size()) - 1)
{
for(int e = j; e < static_cast<int>(hasRepeats.size()); e = e + 1)
{
holder = hasRepeats[e];
hasRepeats[e] = hasRepeats[e + 1];
hasRepeats[e + 1] = holder;
}
hasRepeats.pop_back();
}
}
}
}
