I got an Intel HLS compiler internal assertion failure at line 503 in "FuncMerging.cpp". The assertion message is "Could not legalise this block". Our code is legal. We believe we found a compiler bug. What should I do?

Hi, We will need your funcMerging.cpp files to duplicate this assertion message. Also, provide the steps that you have use. The steps should include the device that you were using. Thanks,
