[comp.windows.x] xlib error

Hi,

	What are these errors for?
Xlib:  sequence lost (0x10055 > 0x5d) in reply type 0x7!
Xlib:  sequence lost (0x10055 > 0x7a) in reply type 0x7!

Thanks in advance.

They are Xlib-internal.  This is almost invariably caused by a wild
pointer bashing an Xlib-internal data structure.  Check your malloc
areas for overruns, check for storing through uninitialized automatic
pointer variables....

What the error actually means is that Xlib sees things happening out of
sequence.  X requests and replies have sequence numbers, which have to
be in sequence, you see....

I have also seen these on systems complied with -DSTREAMSCONN due to
an error in the readv/writev emulation  routines.  I posted a bug fix
for this some time ago;  it's not in any  of the patches, but I got
the polite message back that the bug was fixed in the "development
environment," so I guess it was real.  ... rb
