Re: dpkg 1.8.3.1, fixes sparc sigbus

For those desperately needing this, you can download it from: http://incoming.debian.org/dpkg_1.8.3.1_sparc.deb After this, today begins my quest to purge nfmalloc from dpkg using safer malloc/alloc/obstack functionality. I hope you are doing that in at least head, and maybe in a separate branch, as this could be a big change.

If it does, then the thing to do is start checking the diff between these two versions for possible alignment issues. Run it on an alpha and you'll get alignment warninrs in the kernel log. The part of the code it is having a sigbus(I wish I had an strace) in is not in any code that I modified for the 1.8 series. The actual file it is erroring in has had very little changes since 1.7.2.

Re: dpkg 1.8.1.2 gives SIGBUS on sparc
The following patch(taking from suggestions in bug#74259) is the culprit(as
verified by Ben).

I am not sure if he did my suggestion of moving the long l to the last field
in the union, to see if that helps it.

No, do upgrade it and try to figure out where exactly it goes wrong. Btw, I'll look at this when I get home later tonight. This isn't saying I know what is wrong tho.
