Hi, trying to update from 9.11.3 to 9.11.4 I ran into a strange issue.
Shortly after starting BIND, it is crashing with a SIGBUS error. The debugger shows me the following: > ::status debugging core file of named (64-bit) file: named threading model: native threads status: process terminated by SIGBUS (Bus Error), addr=ffffffff7b2ff92f > $c named`process_cmsg+0x174(11250fda0, ffffffff7b2ffa78, 112511da0, 100819118, 3c, 100870440) named`doio_recv+0x958(11250fda0, 112511da0, 80000000, 100819118, 3c, 100870440) named`internal_recv+0x50c(106bf8f90, 11250fe58, 11250fe58, 1006e77e0, ffffffff7c005240, ff000000) named`dispatch+0xb50(100892700, 0, 0, ffffffff7c005240, ffffffff7c005240, ff000000) named`run+0x18(100892700, 0, 0, 1006b64b0, 0, 1) libc.so.1`_lwp_start(0, 0, 0, 0, 0, 0) Checking with truss on the thread that seems to be causing the issue shows: 20325/7: connect(531, 0x10886C3F8, 32, SOV_XPG4_2) = 0 20325/7: sendmsg(531, 0xFFFFFFFF7AAFEB50, 32768) = 40 20325/7: lwp_park(0x00000000, 0) = 0 20325/7: lwp_park(0x00000000, 0) = 0 20325/7: lwp_park(0x00000000, 0) = 0 20325/7: recvmsg(529, 0xFFFFFFFF7AAFFA78, 32768) = 28 20325/7: Incurred fault #5, FLTACCESS %pc = 0x1006DC384 20325/7: siginfo: SIGBUS BUS_ADRALN addr=0xFFFFFFFF7AAFF92F 20325/7: Received signal #10, SIGBUS [default] 20325/7: siginfo: SIGBUS BUS_ADRALN addr=0xFFFFFFFF7AAFF92F BIND has been compiled as follows (exact compile flags removed): # named -V BIND 9.11.4-P1 (Extended Support Version) <id:2b060b2> running on SunOS sun4v 5.11 11.3 compiled by Solaris Studio 5150 compiled with OpenSSL version: OpenSSL 1.1.0h 27 Mar 2018 linked to OpenSSL version: OpenSSL 1.1.0h 27 Mar 2018 compiled with libxml2 version: 2.9.5 linked to libxml2 version: 20905 compiled with libjson-c version: 0.12 linked to libjson-c version: 0.12 compiled with zlib version: 1.2.11 linked to zlib version: 1.2.11 threads support is enabled The BIND logs don't give any indication of why it is crashing, not even when running it with debug level 3. The environment is: + OS: Solaris 11.3 SRU 32 + Compiler: Oracle DeveloperStudio12.6 + BIND running via chroot As mentioned initially, this has worked fine up until BIND 9.11.3. But using the same built environment and same build flags to build 9.11.4 I started getting these issues. Could someone give a clue whether that's more likely to be an issue with my environment, or in the code ? Regards Marc
