IT10534: SEGV IN ROUTINE_FIND_UE_ID()/ROUTINE_GETENV2() WITH FIX FOR APAR IT05505

APAR status

• Closed as program error.

Error description

• When running nosql queries through wire listener with the fix
  for APAR IT05505, server can segv in routine_find_ue_id(), but
  stack will often only include routine_getenv2() as
  routine_fine_ue_id getting in-lined into routine_getenv2()'s
  frame.  Can also see some -392 errors in onstat -g sql/-g ses
  output before SEGV's.
  
  Stacks for failures might look something like this (but since we
  are referencing freed memory, there could be a bit of variety on
  where things are detected)
  
  
  afhandler
  affail_interface
  mt_ex_throw_sig
  afsig_handler
  (Linux) <signal frame>
  routine_getenv2
  decode_btree_op
