Ok, this actually is a bug in libpam-smbpass, not in swat. When recompiling the packages with debug info, the backtrace from swat is:
#0 0xb7217600 in ??

Now, when looking at libpam-smbpass.so symbols with nm, this gives the following iconv-related output: 0008fe20 t close_iconv_convenience 0008fd4c T get_iconv_convenience 00207a80 B global_iconv_convenience U iconv@@GLIBC_2.1 U iconv_close@@GLIBC_2.1 000a111b t iconv_copy U iconv_open@@GLIBC_2.1 000a1057 t iconv_swab 0007c01a T init_iconv 000a0364 t lazy_initialize_iconv 000a03ff T smb_iconv 000a0af6 T smb_iconv_close 00090085 T smb_iconv_convenience_reinit 000a0abc T smb_iconv_open 000a0686 T smb_iconv_open_ex 000a0600 t smb_iconv_t_destructor 000a0389 t sys_iconv Again, note the t close_iconv_convenience, which as far as I understand says that libpam-smbpass contains close_iconv_convenience in it's text section, so there's a copy of that call in libpam-smbpass. Now, if libpam-smbpass is loaded, it seems like swat uses the wrong version of that call, and things go wrong. If you comment out the libpam-smbpass line in /etc/pam.d/common-auth, The crash is gone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1015935 Title: SWAT segfaults when trying to view full configuration To manage notifications about this bug go to: https://bugs.launchpad.net/samba/+bug/1015935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
