`redis-server` crashes when using `UNWIND`

       Please report the crash by opening an issue on github:

  Suspect RAM error? Use redis-server --test-memory to verify it.

Am I using UNWIND correctly?

Hi @narayanacharya6, the commit you've referred to is quite recent,
the stack trace (Map_Clone) doesn't make much sense, I don't see where the Map data structure is used in the query.

I've tested your query sequence against the edge docker image which reflects current master branch

docker run -p 6379:6379 -it --rm redislabs/redisgraph:edge

Would you mind verifying from your end?

Yes, I cloned the repo last week and built the .so file.

Any suggestions for how I can investigate this?

Hi @swilly22 , I updated my code to the latest commit on master - 7d550c74 and ran the same series of commands, redis-server crashed again. This time the bug report complains about SI_CloneValue.

=== REDIS BUG REPORT END. Make sure to include from START to END. ===

Also, I ran the command sequence against the edge docker container and things work as expected.

My setup with macOS might be an issue here. I had to do some hacky business to build the RedisGraph project on macOS.

[swilly22]

@narayanacharya6 can you please expand on the hacky business ?

[narayanacharya6]

@swilly22 I ran into a few issues with running make directly. From skimming through the README, I understood that there will be a few things I might need to do differently because I was on macOS. Below is a list of things, from memory, I did to get things working. I should add that I am pretty new to building C/C++ projects, so please let me know if I could have done things better.

1. git clone --recurse-submodules -j8 https://github.com/RedisGraph/RedisGraph.git

2. brew install llvm libomp

After this, I tried running make CC=/usr/local/opt/llvm/bin/clang but still ran into errors about fopenmp and libomp - clang: error: unsupported option '-fopenmp' and ld: library not found for -lomp clang-11: error: linker command failed with exit code 1

3. After stumbling through many different blog posts and SO answers, the suggestion here - https://github.com/Rdatatable/data.table/wiki/Installation#step-3 worked for me. I set the below env variables and then ran make

export LLVM_LOC=/usr/local/opt/llvm
export CC="${LLVM_LOC}/bin/clang -fopenmp"
export CXX="${LLVM_LOC}/bin/clang++ -fopenmp"
export CFLAGS="-g -O3 -Wall -pedantic -std=gnu99 -mtune=native -pipe"
export CXXFLAGS="-g -O3 -Wall -pedantic -std=c++11 -mtune=native -pipe"
export LDFLAGS="-L/usr/local/opt/gettext/lib -L${LLVM_LOC}/lib -Wl,-rpath,${LLVM_LOC}/lib"
export CPPFLAGS="-I/usr/local/opt/gettext/include -I${LLVM_LOC}/include -I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include"
make

I am guessing some of the flags I set here might have caused an issue with my build.
