[gem5-users] Decreasing DerivO3CPU.fetchWidth

Hi,

I am using DerivO3CPU and I want to configure it to fetch fewer number of
instructions than the default in order to simplify my experiments.

When I set the "fetchWidth" parameter to 4 (the default is 8),
gem5 stops by an assertion failure "Assertion `skidBuffer[tid].size() <= skidBufferMax' failed"
at cpu/o3/decode_impl.hh:410.

Do I need to set some other paremeters to decrease the number of insts fetched,
or does it seem like a bug of gem5?

Best regards,

Soramichi
