[Pyrex] Mem problem.

[Pere Urbón Bayes]

Dear pyrex community, my name is Pere and I'm porting an internal lib to
 python via pyrex. I could port a little part ( the simple case ) but
when I try to do it with the large case it doesn't work. When I run with
the large case I get all the time this error:

purbon at ccd-purbon:~/workspace/ubc/PyUBC$ ./test.py
1024
<type 'list'>
*** glibc detected *** free(): invalid next size (normal): 0x081567a0 ***
Avortat

this could mean that the code was running ok but when python is freeing
the memory there may be some error that i could not find (Im newby with
python and pyrex, ;>).

When I run this case with gdb the bt is:

(gdb) run test.py
Starting program: /usr/bin/python test.py

#10 0x08055824 in Py_Main ()
#11 0x08055032 in main ()

and the source code involved with pyrex is:

if wordLength <= UnsignedIntLength:
	#We are working with an small code
	smallCode=small_kernel(p,wordLength,codeCardinal,...)
	codi = scCode2pCode(smallCode,codeCardinal,limbs)
else:
	#Our code is on the large side.
	largeCode = large_kernel(p,wordLength,codeCardinal,...)
	codi = lcCode2pCode(largeCode,codeCardinal,limbs)
	
return codi

if i take out the large_kernel function then the case works good ...
this could make me supose that the problem could be with the lib, but if
 i run the binary generated with the lib it run without problems.

PD: Sorry for my english, I'm not so good :<..

Regards,
