I ran across a device that did this back in May of this year.  I believe 
it was a fairly recent model because there was another problem with the 
FCP_RSP frame that the vendor corrected pretty quickly.
Not sure if we are allowed to mention what vendor and device that was on 
here, if so I can tell you later.
I can't say whether it was FCP-4 compliant or not - it was at a customer 
site.

FCP-4: FCP_RSP IU Note
FCP-4 still has the following note: 
NOTE 7 - Some early implementations presented the FCP_RSP IU without the 
FCP_RESID field, FCP_SNS_LEN field, and FCP_RSP_LEN field if the 
FCP_RESID_UNDER bit, FCP_RESID_OVER bit, FCP_SNS_LEN_VALID bit, and 
FCP_RSP_LEN_VALID bit were all set to zero. This non-standard behavior 
should be tolerated.
Are there still implementations that present the FCP_RSP IU without the 
FCP_RESID field, FCP_SNS_LEN field, and FCP_RSP_LEN field if the 
FCP_RESID_UNDER bit, FCP_RESID_OVER bit, FCP_SNS_LEN_VALID bit, and 
FCP_RSP_LEN_VALID bit were all set to zero ?
I would really hope that we have moved past this non-standard behavior and 
would like to remove this note.
Thanks?Dave
