Compilation failure

[nocturn9x]

I know the README explicitly states that a lot of the stdlib isn't supported, so I understand if this issue is marked as not relevant, but I was trying to compile my chess engine using nlvm with the following command:
~/nlvm/nlvm/nlvm c --path:src --panics:on --mm:atomicArc -d:useMalloc -o:bin/heimdall -d:outputBuckets=8 -d:inputBuckets=16 -d:hlSize=1536 -d:ftSize=768 -d:evalNormalizeFactor=337 -d:majorVersion=1 -d:minorVersion=4 -d:patchVersion=2 -d:evalFile=../networks/files/mistilteinn-v3-verbatim.bin -d:netID=mistilteinn-v3-verbatim -d:mergedKings=false -d:verbatimNet=true -d:horizontalMirroring=true -d:isRelease -d:danger --deepcopy:on --cc:clang --passL:"-flto -fuse-ld=lld" --passC:"-flto -static -mtune=native -march=native" -d:simd -d:avx2 src/heimdall.nim

The error I get:

Error: internal error: Unknown string literal kind: tyPtr

If you want to replicate this, clone the repo and run make native the first time: it'll set up the dependencies and the git submodule required for a normal build with the standard nim compiler
