Segfault on LLVM setup due to inconsistent clang and dsymutil for darwin x86_64 #1386
Description
Sorry if this is the wrong place to comment, it's my first julia C++ package and it builds fine for all architectures except for x86_64-apple-darwin
The error is a strange segfault after compiling my library with the following command:
c++ --std=c++20 -I./include -Wall -pedantic -O3 --shared ./MyLibrary.cpp -o build/mylibrary_lib.so -fPIC
/opt/bin/x86_64-apple-darwin14-libgfortran5-cxx11/x86_64-apple-darwin14-dsymutil: line 5: 59 Segmentation fault (core dumped) "$@"
clang++: error: dsymutil command failed with exit code 139 (use -v to see invocation)
This is the WORKSPACE:
# uname -a
Darwin pc 14.5.0 Darwin Kernel Version 14.5.0: Wed Feb 13 00:49:00 UTC 2013; root:xnu-9000/RELEASE_X86_64 x86_64
I checked clang version from WORKSPACE and it is 18.1.7:
# clang --version
clang version 18.1.7 (/home/tim/.cache/BinaryBuilder/downloads/clones/llvm-project.git-1df819a03ecf6890e3787b27bfd4f160aeeeeacd50a98d003be8b0893f11a9be 768118d1ad38bf13c545828f67bd6b474d61fc55)
Target: x86_64-apple-darwin14
Thread model: posix
InstalledDir: /opt/x86_64-linux-musl/bin
I checked dsymutil and it seems old...
# dsymutil --version
LLVM (http://llvm.org/):
LLVM version 8.0.0svn
Optimized build.
Default target: x86_64-apple-darwin6.8.0-60-generic
Host CPU: znver1
I don't know how these things are installed together, but maybe somehow this dsymutil version could be upgraded?
My solution is to remove -g from my compilation line only for x86_64 Darwin, since it works fine on the others and it helps to have debugging symbols on the library.
Thanks a lot!
