[NSMapTable
mapTableWithKeyOptions:NSMapTableObjectPointerPersonality
valueOptions:NSMapTableStrongMemory]
(reading the doc for NSMap, I figured these are the right options)
However, when trying to fetch an object with a void* key to check
for its presence (using the C api as recommended)
NSMapGet(myMap, aKey);
I get an instant crash and looking at the stack trace, it's because
aKey is being sent an ObjC message, to which it will hard time
replying since it's not an NSObject in the first place.
That’s because you’ve marked the keys as being object pointers; you’ve
got your key and value pointer functions reversed.
(Also be sure you want the StrongMemory personality, and not
OpaqueMemory.)
