Well, in fact I did manage to debug this further. :)
The problem is that on sparc64 and -CURRENT, every executable segfaults in
_rtld
init_rtld
relocate_objects
reloc_non_plt
mmap
__getosreldate
It appears that __getosreldate was added five days ago, which may explain
why the breakage on sparc64 hasn't been reported yet. (I am ccing peter@
since he committed this.)
If I apply the following patch, then rebuild libc, things are more or less
ok again. Of course this patch is very suboptimal, I am just trying to
point out where the problem is.
