leezu opened a new issue #17988: Row-sparse constant initializer accesses out of bound elements URL: https://github.com/apache/incubator-mxnet/issues/17988 ## Description CI with updated toolchain (ie #17984) catches the bug. `vector: :_M_range_check: __n (which is 4) >= this->size() (which is 4)` ### Error Message ## To Reproduce Build with this simple patch ``` diff diff --git a/src/c_api/c_api_executor.cc b/src/c_api/c_api_executor.cc index afc64f73d..41193b596 100644 --- a/src/c_api/c_api_executor.cc +++ b/src/c_api/c_api_executor.cc @@ -809,7 +809,7 @@ int _SimpleBindImpl(SymbolHandle symbol_handle, ret->ret_vec_charp.push_back(ret->ret_vec_str.back().c_str()); } *shared_buffer_len = shared_buffer_map.size(); - *updated_shared_buffer_handle_list = &(ret->ret_handles[nd_idx]); + *updated_shared_buffer_handle_list = &(ret->ret_handles.at(nd_idx)); *updated_shared_buffer_name_list = &(ret->ret_vec_charp[0]); } ``` OR follow the instructions in https://github.com/apache/incubator-mxnet/issues/17987 to trigger this via glibc assertions in debug build. Wonder if this is related to https://github.com/apache/incubator-mxnet/issues/14189 CC: @eric-haibin-lin
