etags crashes (probably) on objective-c.
recipe on cmd.exe
>svn co svn://svn.gna.org/svn/gnustep/trunk gnustep

>cd gnustep
>find . -iname "*.[mh]" -print | c:\EMACS\NTEmacs\bin\etags.exe -

etags also crashes on cocotron source. (hg clone http://cocotron.googlecode.com/hg/ cocotron)
I found this on NTEmacs but etags also crashes on Mac OS X. (Segmentation fault: 11)
