I have a couple: 1. I was working as an intern at a router company (basically doing manual QA of software releases). One day one of the software developers comes by and wants to see how hard it would be to add a feature (IP address autonegotiation for point-to-point links). The code already existed in a library, but there was not official way to enable it. The developer did mention that it could happen automatically if the up address was unspecified. I was able to get it active by creating a virtual interface with a manually set IP address, setting the point-to-point link to use the same IP address as the virtual interface, then deleting the virtual interface. 2. I was working on a Government funded research project and some other company was responsible for developing the board support package. The board we were working on had 1 ARM core and a 7-core DSP in a NUMA configuration. I had a processing pipeline that split the processing between cores so that each core handled a different part of the chain. The full code did not fit in DSP memory, so we had separate images for each core. I was seeing crashes every time one of the DSP cores finished handling a message. Eventually I was able to determine that the messages passed between cores by the platform were actually C++ classes with a virtual destructor. My work-around was to overwrite the first 4 bytes of any message the DSPs received with 4 bytes from an empty reference message created locally. That overwrote the vtable and prevented the crash.
