Updated to the testing version of cygwin1.dll, rebooted, still seeing this dig error (updating the cygwin1.dll file may have been superfluous.)
/home/keith>uname -a CYGWIN_NT-6.1-WOW windows-machine 2.9.0(0.317/5/3) i686 Cygwin /home/keith>>dig +short -x 127.0.0.1 0 [main] dig (7444) C:\cygwin\bin\dig.exe: *** fatal error - cygheap base mismatch detected - 0x612EC408/0x84C408. This problem is probably due to using incompatible versions of the cygwin DLL. Search for cygwin1.dll using the Windows Start->Find/Search facility and delete all but the most recent version. The most recent version *should* reside in x:\cygwin\bin, where 'x' is the drive on which you have installed the cygwin distribution. Rebooting is also suggested if you are unable to find another cygwin DLL.
