Re: [HACKERS] SIGSEGV in 'select * from pg_user'

I have just cvsuped the source tree and have tried some tests.

I saw this too on my LinuxPPC box. In my case, just doing:

    select * from pg_user

crashes the backend. The backtrace shows it crashed in chunk_free()
while committing the transaction. I guess something messed up the
tables managed by malloc().

Talking about the regression, two tests (constraints, select_views)
produced core dump. Seems no difference even after applying Bruce's
latest patches.
