Hi Amar,
So fix is what I did first, but someone was wondering about the
additional cost of the alignment calculation in the memory allocation
path. (Though, the unaligned write of the trailer might be as many
cycles of slowdown as a roundup calculation on platforms that handle
unaligned
Thanks for the initiative Paul. Let me answer the major question from the
thread.

Ideal one is to fix it, as we do use mem-pool info to identify leaks etc
through statedumps of the process. Remove can be an option on SPARC to
start with if fixing is time
Hi,
The magic trailer added at the end of memory allocations in mem-pool.c
doesn't have its alignment ensured. This can lead to SIGBUS and
abnormal exits on some platforms (e.g., SPARC64).
I have a patch to round-up the header and allocation size to get the
right alignment for the trailer
