Thank you Lang. I attached the ELF object file here for your reference. Here is the IR dump of JittedOpExpr LLVM function. IrExprGetValue1 LLVM function calls to external function expr->evalfunc(expr, econtext, isNull, isDone); which should be pointed by 0x7fe4801fa1f8. However, only the first time MCJIT generated object point to expr->evalfunc but second time when program load from object cache does not. In the second time, b...
