MWE:

```julia
mutable struct O end;

fnc() = (a = O();finalizer(x -> error("uff! $x"), a);finalize(a));

# I want to suppress all error messages:
for i in 1:2
  try 
    fnc() 
  catch end
end

# Output is -> 
# 0.7.0-rc1.15 ->
error in running finalizer: ErrorException("uff! O()")
error in running finalizer: ErrorException("uff! O()")
# 0.6.1 -> (empty as expected ;) ) 

```
