try with CFLAGS="-pipe" ?
please try 4.0.7 too
As far as I understand, the -pipe option to gcc only affects the compilation process. The tools seem to build fine, but give the "Broken pipe" at runtime. Same problem with 4.0.7.
Can you run: strace -ff <your useradd command> &> trace.txt and attach the trace.txt here.
Created attachment 50926 [details] strace output This is using shadow-4.0.7. I discovered that useradd and userdel both work fine if nscd is not running, but fail with the attached strace when nscd is running.

useradd seems to work for me by hand, but I get the broken pipe issue when portage adds a user
*** Bug 92650 has been marked as a duplicate of this bug. ***
it wouldnt work for me neither by hand or when portage does that. with nscd disabled it works fine. should it be filed as glibc issue as nscd is part of the ebuild ?

I have the problem dbus with with shadow-4.0.7-r1 too. I could successfully do /etc/init.d/nscd stop.
I can confirm this problem. stopping nscd helps. btw, easy test: useradd xxxxxx userdel xxxxxx with nscd runnig, it shows that "broken pipe".

Had the same problem and found BUG #66182. We are running the following software: sys-apps/shadow-4.0.7-r2 sys-libs/glibc-2.3.5 sys-kernel/gentoo-sources-2.6.11-r9 ~x86 2005.0 have a look at comment #2 in BUG #66182. doing this and re- starting nscd resolved the problem on our machine. at least the last 5 tests i ran with user/group/add/del went out fine :-) perhaps this can help to solve the problem... regards andre
update to comment #17: forget this comment - after 10 more tests we again got a broken pipe :-(((

the reason earlier versions didnt fail is because they still use the old path to the nscd socket (/var/run/.nscd_socket) if you guys want, you can comment out the sed at the end of src_unpack where we update the path of the socket and re-emerge shadow to work around this issue ...

(In reply to comment #21) > the reason earlier versions didnt fail is because they still use the old path to > the nscd socket (/var/run/.nscd_socket) Then connect() call from strace output should have failed. It gets a SIGPIPE after a write. Looks like nscd closes the connection.
it gets a sigpipe after the second write ... if it were a connection issue i imagine the first write would have failed too
connect() would have failed too. But if path was wrong before, that meens nscd never was exposed until then. It looks like an upstream bug (caching issues and these sigpipes)
shadow-4.0.7-r2 broke it for me, shadow-4.0.5-r3 worked fine :/
gee, maybe you should read comment #21 where i explain why earlier versions of shadow 'work'
Fixed in shadow-4.0.7-r3.
