[Pkg-allegro-maintainers] Bug#382952: messages "Xlib: unexpected async reply" from allegro

[Emmanuel Anne]

Package: liballegro4.2
Version: 2:4.2.0-5
 
> Allegro gives this message randomly when launching a program using its
> gui features (like raine : http://www.rainemu.com/) :
> Xlib: unexpected async reply
> 
> Well apparently this message is because of Xlib calls made from

> before the X11 window appears, but it doesn't happen all the time (I'd
> say maybe 1 time on 3 launches ? - rather often).
> Once you get this message, the program is frozen, and you have to kill
> it with Ctrl-C.

 Rectification : the problem happens also in allegro-4.2.0 vanilla, I
 was wrong. The easiest way to reproduce it is to run the program from
 gdb, then it happens almost 50% of the time when starting it, it's much
 more rare outside of gdb.

 So forget this report, it's not related to debian, it's related to
 allegro.
