Problem description & steps to reproduce

when i used "cmake -B build -DCMAKE_BUILD_TYPE=Debug" to build debug-mode and run the deepseekv2-lite model, It doesn't work properly anymore.
After some basic debugging, I found that during the traversal of the computation graph, specifically while applying the SiLU operation to the ffn-moe-gate (executing the node ffn_moe_silu-1), a numerical overflow occurred in the operand x, causing the program to crash.
This issue appears unrelated to debug mode, as switching to release mode allowed the program to run, but the output was incorrect：”<｜begin▁of▁sentence｜>Hello my name is!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!“
