i kept investigating, based on the test i've made, im almost sure, 99%, that the increase in memory usage is due to the segmentation of the expressions.

I don't think the problem has anything to do with GiNaC. Hint: try sticking ints (instead of ex*) into that map. Check the memory usage, and compare it with your calculations. Use a different data structure (perhaps hash map or a sorted array), and store ex instead of pointers. Best regards, Alexei
