Subject: scummvm: fails to work on armhf, ARM ASM is buggy [PATCH]

Date: Mon, 23 Feb 2015 14:44:10 +0200

[Message part 1 (text/plain, inline)]

Package: scummvm
Version: 1.7.0+dfsg-1
Severity: grave
tags: patch

I have been trying to run old scummvm games on an old armhf system, but
it was crashing on load with a segfault.

I tried to debug the application and found that at all times, the
culprit are the arm asm optimizations. Disabling these optimizations
makes scummvm run properly on armhf, at least I was able to run both In
diana Jones and the Fate of Atlantis and Beneath a Steel Sky. I attach
a patch but it's only a suggested method, disabling arm optimizations
for all arm* platforms, in the case of Debian, both armel and armhf.

Regards

Hello,

thanks for your report. Unfortunately I cannot verify this issue because
I don't currently possess any armhf hardware capable of running ScummVM.
Hence I also cannot confirm whether your patch actually solves the issue.

I have forwarded this bug report to
https://sourceforge.net/p/scummvm/bugs/6810/. Let's see what the
developers think about this and then we will be able to adjust the
severity accordingly.

Regards,

Markus

I was able to reproduce the bug on a CuBox-i4pro running Debian armhf.

Without the patch, scummvm just showed a blank window and eventually
crashed.

With the patch applied, I was able to play "beneath-a-steel-sky", though
I didn't test it extensively... :)
