 This is acually a bug in the Debian package, because the file isn't
 compiled with -O2 as policy mandates, and the error only occurs at -O0
 ;)
 
 Here's a test case:
 
 struct WordList {
     char c[320000];
 };
 
 void merge(struct WordList);
 
 void merge_file()
 {
     struct WordList w;
     merge(w);
 }
 
 The problem is still there in g++ 3.4 20030423. It also occurs with
 gcc -g.
 
 The author should probably also consider not passing 320k large
 structures by value...
