CVE-2013-4237, BZ #14699: Buffer overflow in readdir_r
broke dirent on sparc.
I suspect it has something to do with alignment. On 32-bit
sparc things must be aligned on a 64-bit boundary even though
"long" is only 32-bit. So that might have something to do
with the issue.
Sorry about that. Can you post strace output showing the complete
buffer that arrives from the kernel?
