Bug#728710: jackd2: Bus error w/ POST_PACKED_STRUCTURE on powerpc G4 32bit
Hi, I've just seen this bus error happen on a MIPS CI20. Using packed structs (or any misaligned memory) will likely cause a SIGBUS on those machines. Is it possible to fix this on mips machines as well? The define to check would be __mips__ (which is defined on all mips machines including 64-bit). Thanks, James signature.asc Description: This is a digitally signed message part

Nevertheless this small patch fixes the bus error and jack is running fine now with jessie. Thanks for reporting back. I've applied the patch to upstream jackd2, it will be included when we sync the next time (we just synced today prior to inclusion).

Hi, please apply the patch above from Adrian (identical with the attached one) also to jessie. I run into the same bus error with a freshly installed jessie on my powerpc (1GHz Powerbook, G4). Nevertheless this small patch fixes the bus error and jack is running fine now with jessie. I'm really happy that this patch was already existing... Thank you very much.

Bug#728710: [Jack-Devel] Bug#728710: jackd2: Bus error w/ POST_PACKED_STRUCTURE on powerpc G4 32bit
I will recompile jack this weekend to see if I can work that out. Here are the defines of gcc: gcc -dM -E - /dev/null |grep ppc\|PPC\|powerpc #define _ARCH_PPC 1 #define __PPC__ 1 #define __powerpc__ 1 #define __PPC 1 #define __powerpc 1 #define PPC 1 #define powerpc 1 Can we assume that __powerpc__ is 32 bit only?

Maybe not for the same causes, but the fix does work. I just got myself a dual Powermac G4 out of a garbage bin, and immediately installed debian and jackd2. It fails with an obscure Bus error; since I also own a raspberry pi, I first tried to patch source with the same fix, and it works. See Usage of __attribute__((__packed__)) causes bus error on ARM: http://trac.jackaudio.org/ticket/295 The issue seems to be related to arm; however the bug *seems* to hit at the same time: Jack: JackEngine::NotifyAddClient: name = system Bus error The Raspberry bug has been workaround in: https://github.com/jackaudio/jack2/commit/2f7d512b419cb75cef2e27db872d641de6e7aa0d +#if defined(__arm__) +#undef POST_PACKED_STRUCTURE +#define POST_PACKED_STRUCTURE +#endif /* __arm__ */ The comment for the commit also states: Since it's only used for mixed 32/64bit jackd installations and we're not facing such a scenario on ARM, there's little use to worry more atm. Modifiying source to #undef #define it unconditionnally did the trick. Bug report tagged as patch, but I don't know the correct flag.
