Hi,

I noticed these warning on my randconfig logs of some builds :

..

drivers/usb/core/hcd.c: In function 'usb_hcd_poll_rh_status':
include/asm/string_32.h:65: warning: array subscript is above array bounds

net/netfilter/nf_conntrack_proto_sctp.c: In function 'sctp_packet':
net/netfilter/nf_conntrack_proto_sctp.c:374: warning: array subscript is above array bounds

drivers/acpi/tables/tbfadt.c: In function 'acpi_tb_create_local_fadt':
include/asm/string_32.h:65: warning: array subscript is above array bounds

...

Regards,

Gabriel

Sounds like a known and already fixed bug in gcc.

Can you confirm that they go away when you build your compiler from the head of the gcc 4.3 SVN branch?

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.

I cannot do that right now but I'll build SVN 4.3 tomorrow and report back.
