I know of two others...
1. When Credit Cards were released in Australia during the 70's, there was a bug where if you overpaid your credit card such that it went into credit, this credit amount reduced your available credit limit. For example, if you owed $100 and had a limit of $1,000, then paid $200, your available limit would now be only $900. Thus, with the original values, and you paid $1200 your available limit would be $1000-$100=$900 then paid $1200 would give you -$300 available meaning you would be overdrawn rather that $300 credit and either $1,000 limit or $1,300 limit.
2. On 29 February 1976, a mini-computer I worked on refused to accept the 29 February 1976 date entry until the OS was patched by the supplier. Fortunately this was done here in Australia quickly and conveyed over the phone to frantic operators.
Do you know of any others???

Data General's MV/2000 minicomputer didn't handle leap years properly in the clock/calendar chip. It was programmed such that 1986, 1990, 1994, etc. were leap years and 1988, 1992, 1996, etc. weren't.
What made it a pain was that the OS would only get the date/time from the chip at startup. The OS would properly handle leap years.... until you rebooted the machine.
So it might be several days (or weeks) before that reboot... and then no one would notice that the system date was one day ahead (or behind).
