I just got another kernel panic while doing "make build":

cleandir ===> libexec
trap type 0, code = 0xa5, v = 0x1830000
kernel program counter = 0xd3476
kernel: Bus error trap
pid = -1, pc = 000D3476, ps = 2200, sfc = 1, dfc = 1
Registers:
[...register dump and kernel stack dump...]
panic: Bus error
Stopped at	_Debugger+0x6:  unlk	a6
