The following reply was made to PR kern/10166; it has been noted by GNATS.

The symbols seem to be OK for these, but no data is printed for the critical frame(s) (the one shown as calling trap(), and possible one not shown that actually calls trap()). >Is the call in frame #15 (at the end of the transcript) suspicious? No. >[as an aside it seems if I do the break to console I consistently wind >up in random_poll+ef3...I guess I ought to compile that with -g too...] This is garbage. You should wind up at Debugger+0x35 or thereabouts. random_poll doesn't contain any addresses beyond random_poll+0x50.
