Recent changes in libthr broke base bind package tools and named on amd64

Vladimir Sharun-2
I've recently installworld my test setup and found bind tools: dig, host hangs during usage (latest bind 9.8.2 in -CURRENT base. The same with named too. Replacing /lib/libthr.so.3 with previous build (26 march) eliminates the problem.

backtrace every time the same:
(gdb) bt
#0  0x000000080123ae4c in kevent () from /lib/libc.so.7
#1  0x000000000052a250 in ?? ()
#2  0x0000000800d64cdd in pthread_create () from /lib/libthr.so.3
#3  0x0000000000000000 in ?? ()
Error accessing memory address 0x7fffff7fc000

Hang processes can be killed only by SIGKILL

I see correlated messages in this list with subject "recent update breaks some ports". I can assume they use libthr as well.

The whole system compiled (in my case) with stock gcc 4.2.1, the kernel with the base clang. btw buildworld fails with clang.


# uname -rp
