OK, the rest of that line of code is the first reference to nm since the 
DECODE_FILE in the block that deals with expansion of ~.  Does the crash 
happen only when opening files in your home directory?

Stefan's fix looks good to me, but I'm not sure how to force a situation 
where there is even the possibility of GC happening in DECODE_FILE, let 
alone forcing GC to definitely occur in there, so I can't test for 
sure.  What is your locale-coding-system set to, and what path does HOME 
expand to?  Also, do you use any arguments to configure or make, and 
have you set any gc or coding-system related variables in .emacs?  Does 
the crash occur if you start Emacs with the -Q option?
