My Squeak crashes doing this, both in 32 and 64 bits, in
primitiveSlotAt/mustMapMachineCodePCcontext.

In step 4 of Hernan's instructions I executed "self createMethod" in an
inspector on the debugger (because we don't have the "create" button
anymore in Squeak apparently).

Here's the 64 bit crash:

4   libsystem_platform.dylib       0x00007fff8615552a _sigtramp + 26
5   ???                           000000000000000000 0 + 0

9   org.squeak.Squeak$(VM_MONIKER) 0x000000010c7c0891 interpret + 631

And this is the 32 bit one:

4   libsystem_platform.dylib       0x9028579b _sigtramp + 43
5   ???                           0xffffffff 0 + 4294967295
