[Pkg-alsa-devel] Bug#1054896: libasound2: alsa 1.2.10-1 segfaults on i386

[Petra Rübe-Pugliese]

Package: libasound2
Version: 1.2.10-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

Since update of the alsa packages
        libasound2
        libasound2-data
        alsa-utils
        libatopology2
from v1.2.9-1 to v1.2.10-1 all sound programs fail with a
segfault (see typical output below.)

This happens reproducibly on four different i386 computers
(this Thinkpad T420, two older Thinkpads T41, and an old PC).
I cannot tell if any other architecture is affected.

Downgrading of the four packages to v1.2.9-1 solves the problem.

Typical output:

    ~ > play /usr/share/sounds/alsa/Noise.wav
    Segmentation fault
    ~ > aplay /usr/share/sounds/alsa/Noise.wav
    Segmentation fault
    ~ > play /usr/share/javascript/mathjax/unpacked/extensions/a11y/invalid_keypress.mp3
