I'm not sure the target in use here will reliably crash over time, but it does right now, and that seems reasonable...? Example crash: ``` file_test: external/+llvm_project+llvm-project/clang/lib/Driver/ToolChains/Darwin.h:505: bool clang::driver::toolchains::Darwin::isTargetWatchOSBased() const: Assertion `TargetInitialized && "Target not initialized!"' failed. ``` Stack fragment: ``` ... #10 0x0000562ba07dec33 isTargetWatchOSBased /proc/self/cwd/external/+llvm_project+llvm-project/clang/lib/Driver/ToolChains/Darwin.h:505:5 #11 0x0000562ba07dec33 clang::driver::toolchains::DarwinClang::addClangWarningOptions(llvm::SmallVector<char const*, 16u>&) const /proc/self/cwd/external/+llvm_project+llvm-project/clang/lib/Driver/ToolChains/Darwin.cpp:1188:7 #12 0x0000562ba072afc7 clang::driver::tools::Clang::ConstructJob(clang::driver::Compilation&, clang::driver::JobAction const&, clang::driver::InputInfo const&, llvm::SmallVector<clang::driver::InputInfo, 4u> const&, llvm::opt::ArgList const&, char const*) const /proc/self/cwd/external/+llvm_project+llvm-project/clang/lib/Driver/ToolChains/Clang.cpp:0:6 #13 0x0000562ba06306d8 clang::driver::Driver::BuildJobsForActionNoCache(clang::driver::Compilation&, clang::driver::Action const*, clang::driver::ToolChain const*, llvm::StringRef, bool, bool, char const*, std::__1::map<std::__1::pair<clang::driver::Action const*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>>, llvm::SmallVector<clang::driver::InputInfo, 4u>, std::__1::less<std::__1::pair<clang::driver::Action const*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>>>, std::__1::allocator<std::__1::pair<std::__1::pair<clang::driver::Action const*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>> const, llvm::SmallVector<clang::driver::InputInfo, 4u>>>>&, clang::driver::Action::OffloadKind) const /proc/self/cwd/external/+llvm_project+llvm-project/clang/lib/Driver/Driver.cpp:6083:10 ... #28 0x0000562b9e479d1f Carbon::BuildClangInvocation(Carbon::Diagnostics::Consumer&, llvm::IntrusiveRefCntPtr<llvm::vfs::FileSystem>, llvm::ArrayRef<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char>>>) /proc/self/cwd/toolchain/base/clang_invocation.cpp:103:21 ... ``` --------- Co-authored-by: Chandler Carruth <chandlerc@gmail.com>
