I've got this when running Cython to generate petsc4py sources.
cython --cleanup 9 -I. -Iinclude -w src petsc4py.PETSc.pyx -o petsc4py_PETSc.c
python: Modules/gcmodule.c:276: visit_decref: Assertion
`gc->gc.gc_refs != 0' failed.
I've tried to manually remove the Cython extension modules
$ rm `find ~/lib/python/Cython -name '*.so'`
but then (I reported this some time ago), things fails (because of
pure-python mode)
cython --cleanup 9 -I. -Iinclude -w src petsc4py.PETSc.pyx -o petsc4py_PETSc.c
Traceback (most recent call last):
File "/u/dalcinl/bin/cython", line 7, in <module>
from Cython.Compiler.Main import main
File "/u/dalcinl/lib/python/Cython/Compiler/Main.py", line 17, in <module>

from Scanning import SourceDescriptor
File "/u/dalcinl/lib/python/Cython/Compiler/Scanning.py", line 14, in <module>
import cython
ImportError: No module named cython
I have no time to dive onto this. I'm in the process of releasing
petsc4py alongside with core PETSc. Could any of you tell me what
cython-devel revision would be more or less safe to use?
