[Android-tools-devel] Bug#933865: adb crashes on startup with SIGBUS

[Till Dörges]

Package: adb
Version: 1:8.1.0+r23-5
Severity: grave
Justification: renders package unusable

Dear Maintainer,

the problem appears to be a regression between 9 (Stretch) and 10 (Buster) as adb worked fine under Stretch and doesn't work anymore under Buster.

When I try to start 'adb' using 'adb devices -l' I get

--- snip ---
user at box:~> adb devices -l
List of devices attached
* daemon not running; starting now at tcp:5037
ADB server didn't ACK

Note: /tmp/adb.1000.log shows exactly what's on stdout/stderr (seen above).


The problem appears to be that adb gets killed by SIGBUS:
