Volatile-ize some plperl variables that must survive into PG_CATCH blocks.
This appears to be necessary to fix a failure seen on buildfarm membersittella. It shouldn't be necessary according to the letter of the Cstandard, because we don't change the values of these variables withinthe PG_TRY blocks; but somehow gcc 4.7.2 is dropping the ball.Discussion:https://postgr.es/m/17555.1485179975@sss.pgh.pa.us
