https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212098 Bug ID: 212098 Summary: Clang crashes on amd64 buildworld 10.3 -> releng/11.0 Product: Base System Version: 11.0-RC1 Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: crees@FreeBSD.org CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org Morning, Getting weird crashes inside different parts of libllvm. If I nuke /usr/obj and try again, it fails somewhere else. Would be surprised if it's a hardware issue as this is the only thing that breaks- very reliable server running zfs, so I feel data corruption is unlikely. Any ideas? https://www.bayofrum.net/~crees/scratch/clangcrash/AArch64MCTargetDesc-e496= dc.cpp https://www.bayofrum.net/~crees/scratch/clangcrash/AArch64MCTargetDesc-e496= dc.sh Path: .Working Copy Root Path: /usr/src/.zfs/snapshot/local URL: file:///exports/freebsd-svn/base/releng/11.0 Relative URL: ^/releng/11.0 Repository Root: file:///exports/freebsd-svn/base Repository UUID: ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f Revision: 304713 Node Kind: directory Schedule: normal Last Changed Author: dim Last Changed Rev: 304690 Last Changed Date: 2016-08-23 18:38:06 +0100 (Tue, 23 Aug 2016) . -I/usr/src/lib/clang/libllvmaarch64desc/../../../contrib/llvm/../../lib/cla= ng/include -DLLVM_ON_UNIX -DLLVM_ON_FREEBSD -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS -DNDEBUG -fno-strict-aliasi= ng -DLLVM_DEFAULT_TARGET_TRIPLE=3D\"x86_64-unkn own-freebsd11.0\" -DLLVM_HOST_TRIPLE=3D\"x86_64-unknown-freebsd11.0\" -DDEFAULT_SYSROOT=3D\"/usr/obj/usr/src/tmp\" -MD -MF.d epend.AArch64MCTargetDesc.o -MTAArch64MCTargetDesc.o -Qunused-arguments -I/usr/obj/usr/src/tmp/legacy/usr/include -std=3D c++11 -fno-exceptions -fno-rtti -stdlib=3Dlibc++ -Wno-c++11-extensions -c /usr/src/lib/clang/libllvmaarch64desc/../../../ contrib/llvm/lib/Target/AArch64/MCTargetDesc/AArch64MCTargetDesc.cpp -o AArch64MCTargetDesc.o Stack dump: 0.
