If you have a gtk_entry *entry[4] then there are only four entries,
entry[0], entry[1], entry[2], and entry[3].  Trying to access entry[4]
goes off the end of the array and who knows what you're actually trying
to use at that point.  Glancing at your code you might just need to make
entry an array of 5 elements not 4.  Remember in C arrays are 0 based so
if you have an array of n elements the last element you can access is
n-1.
