syang-ng opened a new pull request #8930: URL: https://github.com/apache/tvm/pull/8930
This is related to an issue [here](https://discuss.tvm.apache.org/t/crash-triggered-by-8-lines-of-tir-code/10808/5). In a word, function `PrimExpr VisitExpr_(const LoadNode* op)` forgets to check the size of the vector `scope_[op->buffer_var.get()]`, while calling std::vector::back on an empty container will cause undefined behavior. This PR fixed this problem by adding the vector size check before calling `back()`. -- This is an automated message from the Apache Git Service.
