If I change this...
class TestNSArrayInteraction( unittest.TestCase ):
def testNSArrayAllocation( self ):
NSCountFrames()
for i in range(1,1000):
print "c: %s" % i
a = NSArray.array()
b = NSArray.alloc().init()
... to this ...
class TestNSArrayInteraction( unittest.TestCase ):
def testNSArrayAllocation( self ):
NSCountFrames()
for i in range(1,1000):
print "c: %s" % i
a = NSArray.array()
b = NSArray.array()
... the unit test passes! The first test crashes during the second
pass through the loop and, once crashed, the stack is trashed.
Changing the test to...
class TestNSArrayInteraction( unittest.TestCase ):
def testNSArrayAllocation( self ):
NSCountFrames()
for i in range(1,1000):
print "c: %s pre alloc()" % i
a = NSArray.alloc()
print "c: %s pre init()" % i
a.init()
... spews this output:
[bumbox:~/bbum-developer/sourceforge/pyobjc] bbum% python
Lib/Foundation/test/test_nsobject.py
c: 1 pre alloc()
c: 1 pre init()
c: 2 pre alloc()
c: 2 pre init()
Segmentation fault
So -- it is during the second time that the bridge attempts to invoke
-init that it crashes. Specifically, when the NSInvocation object's
-invoke method is fired.
(I'm debugging "out loud" now -- hoping that someone will chime in w/an
"oh, yeah, that's easy!" :-)
