It vanishes on fcn_table.clear .
Starting from the bottom I almost hit the top ;-(
void symbol_table::cleanup (void)
{
// Clear variables in top scope.
all_instances[xtop_scope]->clear_variables ();
/* DISABLED
// Clear function table. This is a hard clear, ignoring mlocked functions.
fcn_table.clear ();
// Clear variables in global scope.
// FIXME: are there any?
all_instances[xglobal_scope]->clear_variables ();
// Clear global variables.
global_table.clear ();
// Delete all possibly remaining scopes.
for (all_instances_iterator iter = all_instances.begin ();
iter != all_instances.end (); iter++)
{
scope_id scope = iter->first;
if (scope != xglobal_scope && scope != xtop_scope)
scope_id_cache::free (scope);
// First zero the table entry to avoid possible duplicate delete.
symbol_table *inst = iter->second;
iter->second = 0;
// Now delete the scope. Note that there may be side effects, such as
// deleting other scopes.
delete inst;
}
