+This is a known issue with JavaScriptCore's WASM In-place interpreter on Linux x64. You can work around it by:
+
+1. Setting \`BUN_JSC_useWasmIPInt=0\` to disable IPInt (reverts to older Wasm interpreter)
+2. Using an aarch64 CPU instead of x86_64
+3. Using \`BUN_JSC_jitPolicyScale=0\` to force JIT compilation (may impact startup performance)
