Failures in LLDB TestProcessSaveCoreMinidump on fresh x86_64 build

[asb]

I've been trying to see what the maximum subset of the LLVM project is I can build and test without hard to resolve failures, but I'm running into issues with some of these LLDB tests.

Build config (running on a current Arch Linux x86_64 host):

    mkdir -p build/release.max && cd build/release.max
    cmake -G Ninja \
      -DCMAKE_BUILD_TYPE="Release" \
      -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;libclc;lld;lldb;mlir;polly" \
      -DLLVM_ENABLE_RUNTIMES="compiler-rt;libc;libcxx;libcxxabi;libunwind;openmp;pstl" \
      -DLLVM_ENABLE_ASSERTIONS=ON \
      -DLLVM_CCACHE_BUILD=ON \
      -DCMAKE_C_COMPILER=clang \
      -DCMAKE_CXX_COMPILER=clang++ \
      -DLLVM_ENABLE_LLD=True \
      -DLLVM_TARGETS_TO_BUILD="all" \
      -DLLVM_BUILD_TESTS=True \
      -DLLVM_APPEND_VC_REV=False \
      -DCOMPILER_RT_INCLUDE_TESTS=ON \
      -DCOMPILER_RT_BUILD_SANITIZERS=False \
      ../../llvm
      cmake --build .

Then ninja check-lldb and I get the failure below. I'm posting as an issue on the hope the problem is obvious to an LLDB dev familiar with this test logic. User error is of course possible, but I don't think the build setup or host is overly exotic:

I've been trying to see what the maximum subset of the LLVM project is I can build and test without hard to resolve failures, but I'm running into issues with some of these LLDB tests.

I've been trying to see what the maximum subset of the LLVM project is I can build and test without hard to resolve failures, but I'm running into issues with some of these LLDB tests.

Build config (running on a current Arch Linux x86_64 host):

    mkdir -p build/release.max && cd build/release.max
    cmake -G Ninja \
      -DCMAKE_BUILD_TYPE="Release" \
      -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;libclc;lld;lldb;mlir;polly" \
      -DLLVM_ENABLE_RUNTIMES="compiler-rt;libc;libcxx;libcxxabi;libunwind;openmp;pstl" \
      -DLLVM_ENABLE_ASSERTIONS=ON \
      -DLLVM_CCACHE_BUILD=ON \
      -DCMAKE_C_COMPILER=clang \
      -DCMAKE_CXX_COMPILER=clang++ \
      -DLLVM_ENABLE_LLD=True \
      -DLLVM_TARGETS_TO_BUILD="all" \
      -DLLVM_BUILD_TESTS=True \
      -DLLVM_APPEND_VC_REV=False \
      -DCOMPILER_RT_INCLUDE_TESTS=ON \
      -DCOMPILER_RT_BUILD_SANITIZERS=False \
      ../../llvm
      cmake --build .

Then ninja check-lldb and I get the failure below. I'm posting as an issue on the hope the issue obvious to an LLDB dev familiar with this test logic. User error is of course popular, but I don't think the build setup or host is overly exotic:

@asb Interesting. I'm going to guess this is related to the most recent changes I landed related to the dynamic loader. As it's failing on an module mismatch, I'll look into this today.

[Jlalond]

@asb Would you mind locally reverting this commit and reporting back?

@asb Would you mind locally reverting this commit and reporting back?

I'll try a fresh build just in case there's anything funky going on, but reverting that patch, doing cmake --build and ninja check-lldb seems to show the same issue still.

EDIT: Of course, a clean build was quick as I was using ccache and there were no changes other than reverting that patch. Issue still there in the clean build with e9c8f75 reverted.
