Davi Arnaut 154fcda822 Bug#51650: crash with user variables and triggers ...

The problem was that bits of the destructive equality propagation
optimization weren't being undone after the execution of a stored
program. Modifications to the parse tree that are based on transient
properties must be undone to enable the re-execution of stored
programs.

The solution is to cleanup any references to predicates generated
by the equality propagation during the execution of a stored program.
