I tried to compile bird with uClibc - on prod machine it crashes with segafault
in malloc. Here is backtrace from coredump:

#0  0xa777b97d in malloc () from /.../libuClibc-0.9.33.2.so
#1  0x0807a856 in bird_xmalloc ()
#2  0x0807a2ad in mb_alloc ()
#3  0x0805bcb3 in bgp_get_bucket ()
#4  0x0805c84d in bgp_rt_notify ()
#5  0x0804a9ef in do_rt_notify ()
#6  0x0804aff3 in rt_notify_basic ()
#7  0x0804b116 in rte_announce ()
#8  0x0804b55c in rte_recalculate ()
#9  0x0804baf4 in rte_update2 ()
#10 0x0805ed62 in bgp_rx ()
#11 0x08074f7e in sk_read ()
#12 0x080756ad in io_loop ()
#13 0x0804a273 in main ()

I'll try to reproduce crash with unstripped version in next few days.
