That particular build is 1.10.3-1 plus the patch for your issue.

A new thread would have been fine :-)
I am assuming you are using the 'de' keyboard layout:

This is a can of worms I don't want to open :-)
At the moment, in the 'de' layout, the tilde deadkey will add a macron
diacritic, e.g. AltGr + "+" + a = Ã£.
I really lack the expertise to determine if this is a bug in xkeyboard-config
(if this german keyboard behavior is something no german keyboard user would
ever expect or want)
The xkb configurations we use come from the xkeyboard-config project, and
aren't trying to be identical to Windows, but to conform to the appropriate
national standards and user expectations.
However, I can see in the case of XWin this is problematic, as it will be
confusing to switch between X and normal Windows windows which have different
As a workaround, you might find specifying -xkbvariant nodeadkeys,
deadgraveacute or deadacute helpful.

I guess this is another symptom of Xlib not understanding the de_DE.CP1252 locale.
This works fine in the de_DE.UTF-8 locale.
I suppose I could patch Xlib to fix this, but I'd rather encourage people to
use UTF-8 locales.

I can't reproduce this problem.
I wonder if this is a problem with handling numpad overlaid onto normal keys
on a laptop keypad? Again, -logverbose 3 output together with xev output
would be helpful.
