Hello, gcc 11.1.0 produces quite a litany of second thoughts when compiling llvmjit_expr.c; is there something in it? (all 'warning' or 'note') llvmjit_expr.c: In function ‘llvm_compile_expr’: llvmjit_expr.c:69:9: warning: ‘build_EvalXFuncInt’ accessing 8 bytes in a region of size 0 [-Wstringop-overflow=] 69 |
