bug#12306: etags crashes

[Viking Rollo]

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)
