Hi Everyone, I'm working with Botan (https://botan.randombit.net/). It is a TLS security library written in C++11. On an old Pentium III machine the self tests are hanging. Other platforms are OK. The strace tail is shown below. I am not that familiar with this type of debugging, and I am looking for a direction to go. I've seen some similar problems on the web, including an indictment of clock_gettime, but the problems lack a good analysis of the problem. My question is, is a futex with a 2147483647 or -1 expected? Where should I be looking to begin to narrow the problem down? Thanks in advance. ************************************************** $ sudo strace ./botan-test block execve("./botan-test", ["./botan-test", "block"], [/* 14 vars */]) = 0 brk(NULL) = 0x9af9000 access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory) readlink("/proc/self/exe", "/home/jwalton/botan/botan-test", 4096) = 30 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7f4e000 ... stat64("src/tests/data/block/noekeon.vec", {st_mode=S_IFREG|0664, st_size=121320, ...}) = 0 stat64("src/tests/data/block/aria.vec", {st_mode=S_IFREG|0664, st_size=2663, ...}) = 0 stat64("src/tests/data/block/des.vec", {st_mode=S_IFREG|0664, st_size=28722, ...}) = 0 getdents(3, /* 0 entries */, 32768) = 0 close(3) = 0 open("src/tests/data/block/aes.vec", O_RDONLY|O_LARGEFILE) = 3 read(3, "# Test vectors from NIST CAVP AE"..., 8191) = 8191 clock_gettime(CLOCK_REALTIME, {1521879372, 559396333}) = 0 futex(0xb78b6a34, FUTEX_WAKE_PRIVATE, 2147483647) = 0 <hang here> ************************* This old machine runs Peppermint, which is a Ubuntu derivative. $ lsb_release -a No LSB modules are available.
