I've been encountering memory corruption when deleting an array created by this template:
%module example
%include "carrays.i"
%array_functions(char, charArray);
Pretty simple right? I generate the cpp with:
swig -c++ -python test.i
And compile with:
g++ -c -fpic test_wrap.cxx -I/usr/include/python2.6
g++ -shared test_wrap.o -o _example.so
I fire up the Python shell and:
>>> import example
>>>
>>> c = example.new_charArray(1024)
>>> example.delete_charArray(c)
*** glibc detected *** python: munmap_chunk(): invalid pointer: 0x00007f381b04ce94 ***
======= Backtrace: =========
/lib/libc.so.6[0x7f381a169cb8]
./_example.so[0x7f381961f505]
./_example.so[0x7f3819621bbe]
python(PyEval_EvalFrameEx+0x4e23)[0x4a2b03]
python(PyEval_EvalCodeEx+0x869)[0x4a4649]
This isn't good at all. BTW I'm on this kernel, if it helps:
Linux dvenable 2.6.28-15-generic #52-Ubuntu SMP Wed Sep 9 10:48:52 UTC 2009 x86_64 GNU/Linux
I've also tried using the wrapper, which seems to be working just fine. I can create instances of this class and when they destruct no evil occurs.
%array_class(char, byteArray);
Thoughts?
