I can confirm and reproduce this with my CUPS server hardy 64 bits.

[Bug 215904] Re: Assertion error in io.c:234: ber_flush2
So after a quick run through the code we find that that the changing of the variable sb-sb_valid (which is what the assert is checking) only happens in one place in sockbuf.c in ber_int_sb_init() and never gets changed again. Therefore we are probably looking at some sort of memory or pointer corruption that ends up twiddling that bit. :( [EMAIL PROTECTED]:~/openldap2.3-2.4.7$ grep -r sb_valid * libraries/liblber/lber-int.h:#definesb_valid sb_opts.lbo_valid libraries/liblber/lber-int.h:#define SOCKBUF_VALID( sb )( (sb)-sb_valid == LBER_VALID_SOCKBUF ) libraries/liblber/sockbuf.c:sb-sb_valid=LBER_VALID_SOCKBUF; -- Assertion error in io.c:234: ber_flush2 https://bugs.launchpad.net/bugs/215904 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openldap2.3 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
