Yes (in pharo):

| error |

error := ((SmalltalkImage current specialObjectsArray) at: 52) at: 21.
{ error. error errorName. error errorCode. }

" an Array(
a PrimitiveError 
#'operating system error' 
nil)"

Pharo doesn't yet have ExceptionInFFICallError in the special objects
array.  If it's ready for porting, I can submit a PR to add it to Pharo.
