[Bug manual/10441] New: Backtraces code example lacks error checking

["christian dot convey at navy dot mil" <sourceware-bugzilla at sourceware dot org>]

On this page:  
   http://www.gnu.org/software/libc/manual/html_node/Backtraces.html
there's a code example near the bottom of the page.

That code makes use of the return value from "backtrace_symbols", without 
first checking if the returned pointer is NULL.

You might argue that this code is just to get the general idea across, and is 
rightfully devoid of error checking.  That's obviously an editorial decision.  
What I can say is that, perhaps like many other people, I followed that 
example's structure without giving it much more thought, and in doing so 
unwittingly introducing a bug into my application.  So for that reason you 
might want to add error handling to the example code.
