Steps to Reproduce

Bug occures in main branch https://github.com/openhwgroup/cv32e41p/commit/bda060eee5bfb22fdbe55029c5e3cf1b62724fff

Reproduce: Compile with Verilator 5.006

Remarks

Assumption: is_compressed_o shall be an output of cv32e41p_merged_decoder and then connected in cv32e41p_id_stage, but not sure if this is correct.
