Bug ID: 240342 Summary: clang++ bus error while building LLVM as part of Julia Product: Base System Version: 11.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: b...@freebsd.org Reporter: alex.ars...@julialang.org I routinely build Julia (https://julialang.org) from source on FreeBSD using ``` gmake -j4 USECCACHE=1 USE_BINARYBUILDER=0 ``` The `USE_BINARYBUILDER=0` option simply tells the build system to download and compile the dependencies from source rather than downloading prebuilt, cross-compiled binaries for the dependencies. Without this option, LLVM is not built from source. Today, doing `git clean -fdx` and rebuilding with the above command proceeded as usual for a while but then failed with the following while compiling LLVM: ``` Scanning dependencies of target LLVMCoverage [ 61%] Building CXX object lib/ProfileData/Coverage/CMakeFiles/LLVMCoverage.dir/CoverageMapping.cpp.o In file included from /usr/home/alex/Projects/julia/deps/srccache/llvm-6.0.1/lib/ProfileData/Coverage/CoverageMapping.cpp:15: /usr/home/alex/Projects/julia/deps/srccache/llvm-6.0.1/include/llvm/ProfileData/Coverage/CoverageMapping.h:643:25: warning: explicitly defaulted copy assignment operator is implicitly deleted [-Wdefaulted-function-deleted] LineCoverageIterator &operator=(const LineCoverageIterator &R) = default; ^ /usr/home/alex/Projects/julia/deps/srccache/llvm-6.0.1/include/llvm/ProfileData/Coverage/CoverageMapping.h:663:23: note: copy assignment operator of 'LineCoverageIterator' is implicitly deleted because field 'CD' is of reference type 'const llvm::coverage::CoverageData &' const CoverageData &CD; ^ clang++: error: unable to execute command: Bus error (core dumped) clang++: error: clang frontend command failed due to signal (use -v to see invocation) FreeBSD clang version 8.0.0 (tags/RELEASE_800/final 356365) (based on LLVM 8.0.0) Target: x86_64-unknown-freebsd11.3 Thread model: posix InstalledDir: /usr/bin clang++: note: diagnostic msg: PLEASE submit a bug report to https://bugs.freebsd.org/submit/ and include the crash backtrace, preprocessed source, and associated run script. clang++: note: diagnostic msg: ******************** PLEASE ATTACH THE FOLLOWING FILES TO THE BUG REPORT: Preprocessed source(s) and associated run script(s) are located at: clang++: note: diagnostic msg: /tmp/CoverageMapping-01cfc3.cpp clang++: note: diagnostic msg: /tmp/CoverageMapping-01cfc3.sh clang++: note: diagnostic msg: ******************** [ 61%] Building CXX object lib/Analysis/CMakeFiles/LLVMAnalysis.dir/PtrUseVisitor.cpp.o gmake[4]: *** [lib/ProfileData/Coverage/CMakeFiles/LLVMCoverage.dir/build.make:63: lib/ProfileData/Coverage/CMakeFiles/LLVMCoverage.dir/CoverageMapping.cpp.o] Error 254 gmake[3]: *** [CMakeFiles/Makefile2:9480: lib/ProfileData/Coverage/CMakeFiles/LLVMCoverage.dir/all] Error 2 ``` The requested attachments are at https://gist.github.com/ararslan/ee6b157f8868a45ad865cfa9b3756f35 -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
