The fix in 1:7.0.1-1 was not complete, there were two additional problems (missing -g and missing BuildID) that are fixed in https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/merge_requests/28 > (There's also #914021, where llvm*-dbgsym do exist but don't actually work; > I don't know whether that will affect 7 after these changes) The above MR creates -dbgsym again and gives you the line numbers in the backtrace back: (gdb) bt full #0 0x00007ffff4d54040 in llvm::sys::Wait(llvm::sys::ProcessInfo const&, unsigned int, bool, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >*)@plt () from /usr/lib/x86_64-linux-gnu/libLLVM-7.so.1 No symbol table info available. #1 0x00007ffff4f020f6 in ExecuteAndWait () at /tmp/llvm-toolchain-7-7.0.1/lib/Support/Program.cpp:41 No locals. #2 0x00000000009cdbc1 in Execute () at /tmp/llvm-toolchain-7-7.0.1/tools/clang/lib/Driver/Job.cpp:335 No locals. #3 0x00000000009ab3c3 in ExecuteCommand () at /tmp/llvm-toolchain-7-7.0.1/tools/clang/lib/Driver/Compilation.cpp:185 No locals. #4 0x00000000009ab58a in ExecuteJobs () at /tmp/llvm-toolchain-7-7.0.1/tools/clang/lib/Driver/Compilation.cpp:236 No locals. #5 0x00000000009bc3ae in ExecuteCompilation () at /tmp/llvm-toolchain-7-7.0.1/tools/clang/lib/Driver/Driver.cpp:1380 No locals. #6 0x00000000006a81c0 in main () at /tmp/llvm-toolchain-7-7.0.1/tools/clang/tools/driver/driver.cpp:462 No locals. (gdb) Using -g instead of -g1 in the above MR gives a proper backtrace, but that would cause build problems due to disk space usage. cu Adrian -- "Is there not promise of rain?"
