Thanks, we are maybe getting closer. It's weird that it works OK with
valgrind. If the valgrind log is empty, though, I'm confused about where
the output you pasted below came from.

Hmm, it would be nice to have line numbers. Can you try compiling with
"-g -O0"?

The function where the problem is deals with whitespace munging. Just a
guess, but do you have any whitespace config options set (e.g.,
apply.whitespace)?
