The problem is seen only on sparc64. 73 de Jeff __ RPM Package Managerhttp://rpm5.org Developer Communication Listrpm-devel@rpm5.org

Have you tried compiling w/ -mstrict-align (assuming you are using gcc)?
This might at the least work around the issue.
I'm not using gcc, although your comment is still useful, since it
got me looking at the alignment options for the Sun compilers. I think if
I wanted to work around this issue, I could use
-xmemalign=8i
Also:
uint32_t hcolor = 0;
...
if (!hge(h, RPMTAG_PACKAGECOLOR, bnt, (void **) hcolor, count)) {
Because hcolor starts out as a 32 bit quantity, it's aligned on a 4-byte
boundary. It's later used in a context where it would need to be aligned
on an 8-byte boundary. If I make the same fix that I did for the
problem I reported last October, changing the type from uint32_t to
uint64_t, the problem goes away.
It looks like there might be another problem lurking nearby with the
int32_t tid = iid;
but I haven't actually triggered that problem yet.
After looking at it further, I don't think int32_t tid is going
to be a problem, since it's used in a different way and not cast to (void
**).
