segfault with ebnf

[jmikedupont2]

I took this example enbf from wikipedia and converted it to read into llama.cpp
but now it just crashes

(gdb) bt                                                                                           #0  0x00005555555c49cf in llama_grammar_init ()
#1  0x000055555559dcfa in llama_sampling_init(llama_sampling_params const&) ()                     #2  0x000055555556dc8a in main ()```

using mistral
gdb --args ../build/bin/main -m ~/.ollama/models/blobs/sha256:6ae28029995007a3ee8d0b8556d50\f3b59b831074cf19c84de87acf51fb54054 --grammar-file ebnf.enbf --keep 512 -n 16000 -c 4096 -f newprompt.txt

Is this still an issue?
