Fix 64-bit alignment problems

ReplyCallBack looks like it's a bad pointer.

The crash is reproducible but it does not occur in the same way every time.
I'm attaching a backtrace of a second crash, caused by the same basic
procedure. This time the server gets SIGABRT.

image showing the problem

"Fatal server error: Out of memory." is reported in Xorg.0.log
Comment 7 Matthieu Herrb 2006-03-12 05:33:27 UTC
If you still care, can you reattach one trace ?
the freedesktop.org disk crash has corrupted all attachments of this report
Comment 8 Timo Jyrinki 2007-02-22 14:26:23 UTC
Marking broken (status null/blank) bugs in xorg with no activity in a long time as fixed. Please reopen if you think it's necessary, but first do a search if a similar bug report is already filed and in a NEW/ASSIGNED state. These bugs do not currently show in most search results as they do not have any status.
