HAWQ-233. Fix HAWQ initialization failed on Centos7
Hi,
We have investigated this issue, and we found the root cause is that gcc-4.8 introduced new feature "-faggressive-loop-optimizations". This optimization feature is enabled by default, and it will break variable length array under some condition.
Similar issue can be found from PostgreSQL 9.2. See the following links for detail:
1. http://www.postgresql.org/message-id/14242.1365200084@sss.pgh.pa.us
2. https://gcc.gnu.org/gcc-4.8/changes.html
3. http://pkgs.fedoraproject.org/cgit/postgresql.git/commit/?h=f19&id=2a75d7af27fdf03e875f76f4c272c8435f565d10
So, we just borrow the idea to fix this issue and create a patch. Please review it.
Thanks.
