概 要一部のLinuxアーキテクチャでメモリアライメントの問題。
詳 細SDLMAME fails to build on several Linux architectures supported by Debian, all with a common problem:

Affected are, at least: ARM, ia64, MIPS and SPARC64.

See the build logs in https://buildd.debian.org/status/logs.php?pkg=mame&ver=0.141-2.

I'm not sure if fixing this would allow builds to succeed for these “exotic” architectures using NOASM, but if it did, it'd pave the path to use MAME on cheap ARM-based boards, which sounds like a good thing. :)

(Note that s390 failed in a totally unrelated way; I'll have a look at that at some point, but I would be incredibly suprised if a single person in this planet does install and run MAME on a s390 server. :)
