coredump: add test Program test-coredump-unwind was modified to map backing files based on virtual addresses instead of segment numbers. The crasher.c is a program that essentially calls some functions and then writes to invalid address causing a crash. Before that, it detects which executables are mapped to which virtual addresses and writes this information to a file suitable for consumption by test-coredump-unwind. The mapping information is obtained form /proc/self/maps, so currently it only works on linux. The test itself is a shell script, which first runs the program and then runs test-coredump-unwind on the resulting core and address space map file to check whether the stack trace obtained from the dump roughly corresponds to what it should look like.
