I just noticed I get the same error from the shimcache plugin, which may be teh 
source of the problem:

$ python2.7  /home/Forensic/volatility-read-only/vol.py --profile=Win2003SP2x86 
-f memdump.raw shimcache
Volatility Foundation Volatility Framework 2.3.1
Traceback (most recent call last):

    197 [main] python2.7 8532 C:\cygwin\bin\python2.7.exe: *** fatal error - cmalloc would have returned NULL

hrmmm i'm not sure why that should even happen.... it will take me a bit to 
install cygwin and see if i can duplicate.

This appears to be an issue in the way that cygwin does memory management.  
Some references are at [1].  There may be a temporary workaround mentioned in 
[2], but that doesn't sound like it's the right way of solving the problem.

It is also possible that the system you're looking at is hitting the memory 
ceiling, in which case it would require us to rework the way the plugins ran to 
use less memory.

For now, I'll run an update of the cygwin library on our build box and produce 
some new binaries for you to test, hopefully within the next week?  Do please 
send me a reminder if I forget though!!!  5:)
