rap7239 opened a new issue, #697:
URL: https://github.com/apache/tvm-ffi/issues/697
Hit a hard segfault on import, via `xgrammar` (a downstream consumer of
`tvm-ffi`) on Apple Silicon. I don't have a source-level root cause, but wanted
to share a clean before/after data point in case it's useful for triage —
possibly related to the aarch64 JIT/ADRP addressing issue described in
Dao-AILab/flash-attention#2084 (also an aarch64 TVM-FFI native crash, different
platform/consumer), though I can't confirm they're the same bug.
**Environment:** macOS 26.6, Apple M4 (arm64), Python 3.12.12,
xgrammar==0.2.3
**Broken:**
apache-tvm-ffi==0.1.13
python -c "import xgrammar"
!!!!!!! Segfault encountered !!!!!!!
File "<unknown>", line 0, in TVMFFIEnvRegisterCAPI
File "<unknown>", line 0, in tvm::ffi::reflection::Metadata::ToJSON(...)
File "<unknown>", line 0, in xgrammar::__TVMFFIStaticInitFunc0()
**Fixed:**
apache-tvm-ffi==0.1.12
`import xgrammar` succeeds cleanly, no crash.
Happy to provide more environment detail or test a patched build if that's
useful.
