Hi Eliot,
Calling #primitiveFailForOSError: fails in the simulator (I guess I'm the first person to use it :-)). It works properly in a real VM, of course.
I've included a stack dump below, but my guess is that PrimitiveError isn't a known class, so isn't guaranteed to be in classTableFirstPage, causing the assertion failure below.
Am I on the right track here?
Thanks, Alistair

OK, I'll take a look. I wonder have you installed the prototype in the specialObjectsArray?

It works properly in a real VM, of > course. I (think) I take this back. It looks like the debug VM will crash in about the same place: $ ~/vmmaker/opensmalltalk-vm/products/debug/cogspur64linuxht/pharo -gdb Pharo.image run Pharo.image GNU gdb (Ubuntu 7.11.1-0ubuntu1~16.5) 7.11.1 Copyright (C) 2016 Free Software Foundation, Inc.

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)"
newArray at: 52 put: #(nil "nil => generic error" #'bad receiver' #'bad argument' #'bad index' #'bad number of arguments' #'inappropriate operation' #'unsupported operation' #'no modification' #'insufficient object memory' #'insufficient C memory' #'not found' #'bad method' #'internal error in named primitive machinery' #'object may move' #'resource limit exceeded' #'object is pinned' #'primitive write beyond end of object' #'object moved' #'object not pinned' #'callback error'), {PrimitiveError new errorName: #'operating system error'; yourself.

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.
