[IBM z Systems] Getting server crash when jit_above_cost =0

2020-04-21 Thread tushar
Hi, We are  getting a server crash on zlinux machine  if we set jit_above_cost=0 in postgresql.conf file after configuring  PG v12 server  with --with-llvm ( llvm-ttoolset-6.0) We configured  PG v12 sources with switch --with-llvm  ( after setting these variables on command prompt )
