In list archives I've read that this may be due to (a) a memory management bug in my code or (b) a bug in Mac OS X. Both of these seem unlikely since I've been shipping that code for 5 years, and the bug in Mac OS X was back in 2004.

First, it would be helpful if you were to indicate which version of Mac OS X this was on. Actually, there's a bunch of information in the crash log header that would be useful.
That said, looking at the disassembly of __CFAllocateObject2(), it seems to only call CFStringCreateWithFormat() with the following format string:
*** NSAllocateObject(): attempt to allocate object of class '%s' failed
No doubt CFStringCreateWithFormat() then failed because it, too, could not allocate memory. I would say you've either smashed your heap so badly that malloc can't work or you really have exhausted your address space (4GB for an apparently 32-bit process).
