According to http://www.debian-administration.org/articles/585, it seems it's a bug in libnss-ldap: This is a problem with libnss-ldap. try libnss-ldapd.

I can confirm that changing to libnss-ldapd seems to solve the problem here.

[Bug 219527] Re: Username completion crashes with libnss-ldap
Test program 3 runs fine, too. But I found out why all the test programs run fine: They use the libc6 malloc(), while bash brings its own: I did apt-get build-dep bash apt-get source bash, then debian/rules in there. After that: [EMAIL PROTECTED]:~/pwent-test/bash-3.2# grep start and end chunk sizes differ * -R bash/lib/malloc/malloc.c:xbotch (mem, ERR_ASSERT_FAILED, _(free: start and end chunk sizes differ), file, line); bash/lib/malloc/malloc.c:xbotch (mem, ERR_ASSERT_FAILED, _(realloc: start and end chunk sizes differ), file, line); So I'd think this is a bug in bash itself.

Yes, that's good. I was also wondering about the missing malloc calls :) I think it would be best if you could take this to the bash-bug mailinglist. They should know how best to debug this.
