2 | /* A test program written to test robustness to decompression of | ||
3 | corrupted data. Usage is | ||
4 | unzcrash filename | ||
5 | and the program will read the specified file, compress it (in memory), | ||
6 | and then repeatedly decompress it, each time with a different bit of | ||
7 | the compressed data inverted, so as to test all possible one-bit errors. | ||
8 | This should not cause any invalid memory accesses. If it does, | ||
9 | I want to know about it! | ||
10 | |||
11 | PS. As you can see from the above description, the process is | ||
12 | incredibly slow. A file of size eg 5KB will cause it to run for | ||
13 | many hours. | ||
