[GitHub] [incubator-mxnet] leezu opened a new issue #18034: QuantizedElemwiseMulOpShape accesses out of bound elements

leezu opened a new issue #18034: QuantizedElemwiseMulOpShape accesses out of bound elements
URL: https://github.com/apache/incubator-mxnet/issues/18034
 
 
   ## Description
   MKLDNN `QuantizedElemwiseMulOpShape` accesses out of bound elements in line 64
   
   https://github.com/apache/incubator-mxnet/blob/ab4f7f6a7335e88034edcf61402aec170cdca5fd/src/operator/quantization/quantized_elemwise_mul.cc#L63-L65
   
   Preventing that invalid access by adding `out_attrs->size() > quantized_elemwise_mul::kOutMin` to the if condition, leads to errors in `infer_shape_pass`.
   
   CI with updated toolchain (ie #17984) catches the bug. See https://github.com/apache/incubator-mxnet/issues/17987 for instructions to reproduce: use recent gcc and build in debug build
