I was inspired by http://embed.cs.utah.edu/creduce/, which takes a big C or C++ program that triggers a bug such as a compiler crash, and reduces it to a minimum example that still produces the bug.
What a lovely idea, I thought, and so I wrote one for perl code, somewhat imperfect, but it worked on a few thousand-line examples that I inserted bugs into.
Now I could use some real examples. I did some surfing through rt.perl.com and it seems that a search for segfault only brings up pre-minimized examples. Does anyone have a useful example lying around? Even better, "I would file this damn bug if only I could reduce this 10,000 line program to a reasonable size..."
EDIT: the code is now published as https://github.com/blekko/perl-reduce
