[yt-users] mac yt installer issues

Sun Dec 5 22:35:56 PST 2010

At the risk of asking another dumb question, I've encountered another
bug with the mac install of yt that I wanted to investigate.  The
installer completed without any further problem, as I mentioned in the
previous email.  Unfortunately, when I go to actually run yt, I get a
strange error:

$ python
Python 2.6.3 (r263:75183, Dec  2 2010, 18:20:57)
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from yt.mods import *
python(29204) malloc: *** error for object 0x101e800e0: pointer being
freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort

Ideas?  I guess I could narrow this down by individually loading each of
the yt modules to find out where the bug is, or at the very least
putting pdb breakpoints, but I wanted to check first to see if other
people had encountered this error.  This is with the latest version of
yt, as I just pulled it from the mercurial repo (unstable).
