Hmm. I'm reminded of a problem on s390x. 64-bit arch, but when dpkg was
initializing some variable, it only did it to the lower(or upper, can't
recall) 32 bits. Later, it blew up.
It's too bad valgrind doesn't work on non-i386.
Is there a debian machine I can access that has this problem? The last 2
times some odd issue came up like this, one turned out to be a dpkg
bug(s390x), and one was a multi-year old bug in libc6 assem(memcpy error, at
the end of the buffer, when using mmap, on alpha). In both cases, it didn't
take me long to track down(not more than half a day).
