A save file that ended in the middle of a value before the "SAVEFILE" field had been loaded would cause a read from uninitialised memory. While technically undefined behaviour this was practically pretty harmless. Fixed by handling unexpected EOF here the same an unexpected EOF anywhere else. This bug could be demonstrated by loading a truncated save file like this in a build with MemorySanitizer enabled: SAVEFILE:41:Simo
This is the README accompanying the source code to Simon Tatham's puzzle collection. The collection's web site is at <https://www.chiark.greenend.org.uk/~sgtatham/puzzles/>. The puzzle collection is built using CMake <https://cmake.org/>. To compile in the simplest way (on any of Linux, Windows or Mac), run these commands in the source directory: cmake . cmake --build . The manual is provided in Windows Help format for the Windows build; in text format for anyone who needs it; and in HTML for the Mac OS X application and for the web site. It is generated from a Halibut source file (puzzles.but), which is the preferred form for modification. To generate the manual in other formats, rebuild it, or learn about Halibut, visit the Halibut website at <https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.
