buildworld panics with yesterday's kernel ...

[Andrew Atrens <atrens@xxxxxxxxxxxxxxxxxx>]

Hi All,

With kern.mmxopt=0, my buildworld's are failing with
'internal compiler error' at random times, and on a
couple of occasions my system has panicked. Here are
the gdb backtraces on the vmcores -


First one (kernel not built for debugging)

(kgdb) bt
#0  0xc01dc299 in dumpsys ()
#1  0xc01dc024 in boot ()
#2  0xc01dc4d8 in poweroff_wait ()
#3  0xc03a6d28 in trap_fatal ()
#4  0xc03a68e5 in trap_pfault ()
#5  0xc03a659b in trap ()
#6  0xc01f55bd in poll ()
#7  0xc03a709a in syscall2 ()
#8  0xc0397b2a in Xint0x80_syscall ()
#9  0x29272e26 in ?? ()
#10 0x0 in ?? ()


Rebuilt with debugging, here are the next two -
