Hi,
I’m trying to use an NSHashTable with weak objects (-weakObjectsHashTable) on
Android, but it’s segfaulting in addObject: on all architectures (ARM/x86).
Does anyone know if this should be supported or what might be going on here?
Following is the backtrace:
frame #5: 0xca4e2b12 libobjc.so`objc_msgSend at objc_msgSend.x86-32.S:120
frame #6: 0xc9befbcd libgnustep-base.so`hashObject(item=0xcacce5a0,
size=0x00000000) at NSConcretePointerFunctions.m:126

frame #11: 0xc9b0074f libgnustep-base.so`-[NSConcreteHashTable
addObject:](self=0xc7d2d1e4, _cmd="C", anObject=0xcac9945c) at
NSConcreteHashTable.m:863
Interestingly, when I use hashTableWithWeakObjects
(NSPointerFunctionsZeroingWeakMemory, deprecated on Apple platforms) instead of
weakObjectsHashTable (NSPointerFunctionsWeakMemory), addObject: works OK, but
the pointer is not zero’d when the object is released.
Thanks!
Frederik
