It was another lazy, rainy winter afternoon, so once again I was looking to make the world of node.js a better place. Browsing the issues, I was struck by the bizarreness of #4291. The user anseki had written a simple script to read the next line the user types into the terminal. If you resized the window running the program while it was waiting for input, the program crashed with a segmentation fault.
Segmentation faults can happen in C when a program makes an invalid memory access. So somehow, resizing the window triggered an invalid C memory access from this Javascript program. Most untoward!
