okay, seems like i found why:
NBExternalAddress>>ulongAt: zeroBasedOffset put: value "Store unsigned 64-bit integer into memory at (receiver's address + ZERO-based offset) using native byte order. Note, there is no range checking "
It should use 32-bit values.. Callback code using ulongAt:put. to store single value at certain address in machine code. Since it stores 64-bit value instead of 32bit, it overrides the instructions which follow, and of course that leads to crash.
Trait aliases.. is wrong:
#longAt:->#nbInt64AtOffset:. #longAt:put:->#nbInt64AtOffset:put:. #ulongAt:->#nbUInt64AtOffset:. #ulongAt:put:->#nbUInt64AtOffset:put:
another reason to get rid of confusion with C types..
Yep indeed... that's the issue ... I have corrected it locally, but I cannot commit it (it seems I'm not in the developers list anymore):
NBExternalHandle variableByteSubclass: #NBExternalAddress uses: TNBMemoryAccessors @ {#byteAt:->#nbInt8AtOffset:. #byteAt:put:->#nbInt8AtOffset:put:. #longAt:->#nbInt32AtOffset:. #longAt:put:->#nbInt32AtOffset:put:. #ulongAt:->#nbUInt32AtOffset:. #ulongAt:put:->#nbUInt32AtOffset:put:} Cheers, Ciprian
