<pre>I cloned the LLVM monorepo into ~/dev/llvm-project and created an out of source
build directory in which I configured the project to enable clang, lldb and
lld. I want to generate coverage information, so I've set
-DLLVM_BUILD_INSTRUMENTED_COVERAGE=ON.
cmake ~/dev/llvm-project/llvm \
-DLLVM_ENABLE_PROJECTS="clang;lldb;lld" \
-DBUILD_SHARED_LIBS=ON \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_BUILD_INSTRUMENTED_COVERAGE=ON \
-DCMAKE_CXX_COMPILER=/usr/bin/clang++ \
-DCMAKE_C_COMPILER=/usr/bin/clang
Then I've built the lldb tartget and it fails (reproducible) with this out of
memory error. What's strange is that I have plenty (18Gig + 10Gig Swap) of
memory free.
