Hi Leslie, This is likely the same problem as was reported in https://bugs.freebsd.org/225054#c8, and fixed by the following patch:
https://svnweb.freebsd.org/ports/head/java/openjdk8/files/patch-hotspot_src_share_vm_services_memTracker.cpp?view=markup&pathrev=459368 Can you please try that out, and see if it fixes it for you too? -Dimitry > On 10 Sep 2018, at 18:20, Leslie Zhai via llvm-dev <llvm-...@lists.llvm.org> > wrote: > > Hi all, > > OpenJDK8 jdk8u-dev[1] is just able to work after compiled with LLVM 3.9.1 for > X86: > > $ ./build/linux-x86_64-normal-server-slowdebug/images/j2sdk-image/bin/java > -version > openjdk version "1.8.0-internal-debug" > OpenJDK Runtime Environment (build > 1.8.0-internal-debug-xiangzhai_2018_09_09_21_08-b00) > OpenJDK 64-Bit Server VM (build 25.71-b00-debug, mixed mode) > > $ strings > ./build/linux-x86_64-normal-server-slowdebug/images/j2sdk-image/bin/java | > grep clang > clang version 3.9.1 (tags/RELEASE_391/final) > > But it failed to work after compiled with LLVM 8 for X86: > > $ ./build/linux-x86_64-normal-server-fastdebug/images/j2sdk-image/bin/java > -version > Segmentation fault > > $ gdb --ex run --args > ./build/linux-x86_64-normal-server-fastdebug/images/j2sdk-image/bin/java > -version > GNU gdb (GDB) Fedora 7.12.1-48.fc25 > ... > Starting program: > /home/xiangzhai/project/jdk8u-llvm/build/linux-x86_64-normal-server-fastdebug/images/j2sdk-image/bin/java > -version > [Thread debugging using libthread_db enabled] > Using host libthread_db library "/lib64/libthread_db.so.1". > > Program received signal SIGSEGV, Segmentation fault. > [ Legend: Modified register | Code | Heap | Stack | String ] > ───────────────────────────────────────────────────────────────────────────────────────────────[ > registers ]──── > $rax : 0x0 > $rbx : 0x0 > $rcx : 0x7ffff7315eb0 → 0x00007ffff6ae30a0 → > <NativeCallStack::print_on(outputStream*)+0> xor edx, edx > $rdx : 0x0 > $rsp : 0x7fffffff9328 → 0x00007ffff6a76822 → > <MemTracker::init_tracking_level()+178> mov edi, ebx > $rbp : 0x7fffffff93c0 → 0x00007fffffff94f0 → 0x00007fffffff9510 → > 0x0000000000000002 > $rsi : 0x0 > $rdi : 0x7ffff7315e70 → 0x00007ffff7315eb0 → 0x00007ffff6ae30a0 → > <NativeCallStack::print_on(outputStream*)+0> xor edx, edx > $rip : 0x7ffff6ae2f5b → <NativeCallStack::NativeCallStack(int,+0> mov > QWORD PTR [rdi], rcx > $r8 : 0x1 > $r9 : 0xf > $r10 : 0x64 > $r11 : 0x0 > $r12 : 0x7fffffffdc88 → 0x00007fffffffe04c → > "/home/xiangzhai/project/jdk8u-llvm/build/linux-x86[...]" > $r13 : 0x7fffffffdca0 → 0x00007fffffffe0bf → "XDG_VTNR=1" > $r14 : 0x7fffffff9330 → "NMT_LEVEL_10535" > $r15 : 0x6 > $eflags: [carry parity adjust zero sign trap INTERRUPT direction overflow > RESUME virtualx86 identification] > $ss: 0x002b $ds: 0x0000 $cs: 0x0033 $es: 0x0000 $gs: 0x0000 $fs: 0x0000 > ───────────────────────────────────────────────────────────────────────────────────────────────────[ > stack ]──── > 0x00007fffffff9328│+0x00: 0x00007ffff6a76822 → > <MemTracker::init_tracking_level()+178> mov edi, ebx ← $rsp > 0x00007fffffff9330│+0x08: "NMT_LEVEL_10535" ← $r14 > 0x00007fffffff9338│+0x10: 0x0035333530315f4c ("L_10535"?) > 0x00007fffffff9340│+0x18: 0x0000000000000001 > 0x00007fffffff9348│+0x20: 0x0000000000602190 → 0x00007ffff5eb7000 → > 0x00010102464c457f > 0x00007fffffff9350│+0x28: 0x0000000000000004 > 0x00007fffffff9358│+0x30: 0x000000066474e551 > 0x00007fffffff9360│+0x38: 0x0000000000000000 > ────────────────────────────────────────────────────────────────────────────────────────[ > code:i386:x86-64 ]──── > 0x7ffff6ae2f4b <print_owned_locks_on_error(outputStream*)+187> add eax, > 0x1f0f00 > 0x7ffff6ae2f50 <NativeCallStack::NativeCallStack(int,+0> mov rcx, QWORD > PTR [rip+0x842781] # 0x7ffff73256d8 > 0x7ffff6ae2f57 <NativeCallStack::NativeCallStack(int,+0> add rcx, 0x10 > → 0x7ffff6ae2f5b <NativeCallStack::NativeCallStack(int,+0> mov QWORD PTR > [rdi], rcx > 0x7ffff6ae2f5e <NativeCallStack::NativeCallStack(int,+0> mov DWORD PTR > [rdi+0x28], 0x0 > 0x7ffff6ae2f65 <NativeCallStack::NativeCallStack(int,+0> add rdi, 0x8 > 0x7ffff6ae2f69 <NativeCallStack::NativeCallStack(int,+0> test edx, edx > 0x7ffff6ae2f6b <NativeCallStack::NativeCallStack(int,+0> je > 0x7ffff6ae2f7b <NativeCallStack::NativeCallStack(int, bool)+43> > 0x7ffff6ae2f6d <NativeCallStack::NativeCallStack(int,+0> mov eax, esi > ─────────[ > source:/home/xiangzhai/project/jdk8u-llvm/hotspot/src/share/vm/utilities/nativeCallStack.cpp+33 > ]──── > 28 #include "utilities/nativeCallStack.hpp" > 29 > 30 const NativeCallStack NativeCallStack::EMPTY_STACK(0, false);
