Subject: Segfault for hdaa on linux-x86-clang-debug (was: testing all valid()s)
On latest git, with a Makefile change disabling address sanitizer to
allow building linux-x86-clang-debug despite of clang's ASAN feature
being broken on fedora, I get this:
$ ./john --format=hdaa --test
Benchmarking: HTTP Digest access authentication MD5 [128/128 SSE2
intrinsics 16x]... Segmentation fault (core dumped)
$ gdb ./john
