Red Hat Bugzilla – Bug 443212
incorrect and/or agressive optimization compile problem
Last modified: 2008-04-20 12:52:01 EDT
Description of problem: I cannot run any Python-based desklet: I get garbage collection errors! If you get errors similar to: python: Modules/gcmodule.c:275: visit_decref: Assertion `gc->gc.gc_refs != 0' failed. Aborted It means your installment of Python has a corrupted garbage collector; it is often caused by incorrect or aggressive optimization during the compilation. See this as well: http://article.gmane.org/gmane.linux.redhat.fedora.mentors/16 Version-Release number of selected component (if applicable): python-2.5.1-15.fc8 How reproducible: Just start a python Desklet: http://adesklets.sourceforge.net/desklets.html Steps to Reproduce: 1. Start a desklet 2. 3. Actual results: python: Modules/gcmodule.c:275: visit_decref: Assertion `gc->gc.gc_refs != 0' failed. Aborted Expected results: Working Desklets Additional info: Compiled adesklets from http://sourceforge.net/project/showfiles.php?group_id=126227 Same adesklets, desklets works perfect in Debian Lenny in a VM (Virtualbox).
Is this gdesklets? I'll reassign assuming yes. I know there's been at least one bug in the gnome python stack, maybe the problem is there ... it's almost guaranteed that this isn't a generic python bug.
This is not a gdesklets related issue. Reporter has compiled adesklets from source and adesklets won't run b/c of the way python is compiled/optimized (according to the adesklets site)??? Assigning back to python component since it is not gdesklets related and adesklets is not part of the Fedora Collection
Reassigning the bug to the right maintainer.
Ok, I understand now ... "adesklets" is an external package and has a bug.
To give some more help, if the adesklets people have a bug logged against _upstream_ python ... and there is an acknowledged code problem and/or optimization problem in python, feel free to paste it and I'll see what I can do to help you in Fedora ... until then, I'm going to assume adesklets is broken.
Hello James, no, the adesklets people have not logged a bug against upstream python. It was from http://article.gmane.org/gmane.linux.redhat.fedora.mentors/16 That was everything trouble related to adesklets that i have found with google. adesklets itself runs fine with, example, Debian Lenny (running in Vbox as Guest, Fedora 8 as Host). It seems that Fedora is the only Distribution where it has trouble. I have filed the bug because i dont like to recompile a stock Python from python.org for myself. And i thought it would be great to have adesklets working in Fedora 9, if you or the Mentor (from the link above) know what is incorrect or too aggressive optimized, so that i can make a adesklets rpm for Fedora and maintain it eventually. If you need more info, tell me. If it is unworthy for you, tell me also please. Thank you for your time.
""" incorrect or too aggressive optimized """ Again, as far as I know there is nothing "incorrect" or "too aggressively optimized" in python ... as far as I can tell these are just words from the adesklets developers that mean "we have a bug in our code that goes away if we recompile python without optimizations". To put it another way, I see a _lot_ of these "GC bugs in python" and I have yet to see one that is actually a python bug. So without some kind of real data, this is just another buggy python extension which you are free to try and run or not.
