Not sure if this is a bug or a feature - seems like a bug.

Using avrdude 4.4.0 to program AtMega8515 via stk500.

Option -U flash:w: used with NO eeprom write request, erases the eeprom forcing an unneccessary reprogram of the eeprom after programming the flash.

This could be because you don't have the "Preserve EEPROM Memory during Erase" fuse set. Please check if this is the case.

Closed as unreproducible, as the OP did not provide information whether the Preserve EEPROM fuse was set or not.
