Here are some of my environment.

$ which clang /Library/Developer/CommandLineTools/usr/bin/clang $ clang --version Apple LLVM version 9.1.0 (clang-902.0.39.2) Target: x86_64-apple-darwin17.7.0 Thread model: posix InstalledDir: /Library/Developer/CommandLineTools/usr/bin $ which lli /usr/local/opt/llvm/bin/lli $ /usr/local/opt/llvm/bin/clang --version clang version 7.0.1 (tags/RELEASE_701/final) Target: x86_64-apple-darwin17.7.0 Thread model: posix InstalledDir: /usr/local/opt/llvm/bin

I rerun the exact commands that you used. But I still get the error.

Does setting LLVM_COMPILER_PATH ensure the correct version of compiler be used? Thanks.

export LLVM_COMPILER_PATH=/usr/local/opt/llvm/bin export CC=gclang ../bash-5.0/configure && make -j2 for i in (find.−executable−and−typef);doecho(find . -executable -and -type f) ; do echo (find.−executable−and−typef);doechoi ; extract-bc $i ; done $ lli bash.bc -c "echo 'test''" Stack dump: 0.

Could you try the bash source code to see if you see the same errors? It should just take a few minutes to configure/compile. Thanks. https://ftp.gnu.org/gnu/bash/bash-5.0.tar.gz > I did a sanity check and run some of the bitcode I complied with gllvm and it seems to work fine under lli. The only issues is to make sure you load all the (external) libraries the bitcode needs. I highly suggest you run a debug version of lli under a debugger and see what exactly happens. -- Regards, Peng -- Jakub Kuderski
