It does, but I haven't had time to boil down the test case. Sorry. Kjell Braden wrote: We are closing this bug report because it lacks the information we need to investigate the problem.

here is an example of code that fails on 64 bit machines running 8.10, but works on 8.04.

I have not been able to replicate the bug on a 64bit ubuntu 8.10 box.
here is the platform info for the machine I tested on using the script

though, but I am not aware of anything that would have changed

[Bug 295719] Re: python-matplotlib: Exception when drawing image on 64-bit system
John, in svn HEAD r6036 fixed this problem, which seems to need a newer numpy version, (PyArray_SimpleNewFromData does not use the same conversion code for the dimensions as PyArray_FromDimsAndData uses) The attached patch fixes this issue for me. Can someone confirm that this does not affect i386? We have to wait for bug 317208 and two more sync requests to be done before we can upload this change, as matpotlib currently FTBFS. ** Attachment added: fix_backendgdb_pointers.patch http://launchpadlibrarian.net/21217636/fix_backendgdb_pointers.patch -- python-matplotlib: Exception when drawing image on 64-bit system https://bugs.launchpad.net/bugs/295719 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 295719] Re: python-matplotlib: Exception when drawing image on 64-bit system
At the moment, only a big complicated one. However, I think Benjamin Drung dug up something worth inspecting. My bet is that he found the problem. Please take a look at the incompatible pointer type problem he found; if that isn't relevant or isn't trivial to fix, I'll boil my code down to a small test case. -- python-matplotlib: Exception when drawing image on 64-bit system https://bugs.launchpad.net/bugs/295719 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you for taking the time to report this bug and helping to make Ubuntu better. The package is build once for i386 and once for amd64. So there should be no 32 and 64 bit libraries mixed.
