I did something stupid!

Know what it was? It was compiling C++ code on a single-user system without knowing barely anything about the language, then running running that code on a multi-user system far later and finding out, hey, I'm segfaulting!

Any way I can try to patch up any possible memory leaks in my normal computer?

Sounds like you're accessing bad/freed memory. Get out a debugger (ie, gdb+valgrind) and figure out where it's breaking, then come back with a backtrace and associated code if you really want help.
