[arch-general] [SOLVED - it's glibc - upstream or Arch?] was Re: xcb_wait_for_reply () from /usr/lib/libxcb.so.1 causing kdesktop crash on x86_64 (is this an upstream issue?)

Guys,

  The problem is glibc-2.13-4. I have about 5 Arch/Trinity Virtualbox VMs. On
one I had not updated, I started Trinity x86_64 and there was NO kdesktop crash.
I then proceeded to update the VM to the current Arch packages which included:

[2011-02-22 11:13] Generating locales...
[2011-02-22 11:13]   en_US.UTF-8... done
[2011-02-22 11:13]   en_US.ISO-8859-1... done
[2011-02-22 11:13] Generation complete.
[2011-02-22 11:13] upgraded glibc (2.13-3 -> 2.13-4)
<snip>
[2011-02-22 11:17] upgraded kernel26 (2.6.37-6 -> 2.6.37.1-1)
[2011-02-22 11:17] upgraded kernel26-headers (2.6.37-6 -> 2.6.37.1-1)
<snip>
[2011-02-22 11:18] upgraded trinity-kdelibs (1220926-1 -> 1222098-1)
[2011-02-22 11:18] upgraded trinity-kdebase (1221507-1 -> 1221588-1)

  On next reboot/restart, I got the kdesktop.kcrash (see current link above). So
then I downgraded glibc (2.13-4 -> 2.13-3), restarted Trinity -> perfect! No
kdesktop,kcrash.

  Do you think this could be a packaging/patch issue with Arch, or do you think
is going to be glibc itself? It looks like glibc to me, but I thought I'd ask
first here before going to the glibc folks in case it was something that you
guys wanted to look at.

  Thanks.
