This was opened on SourceForge as bug #1760481.

I've added a dynamic string allocation suite ("dstring") to libdkim and 
attached a patch to that bug which makes use of it when processing headers 
inside dkim-canon.c.  In dkim-filter I've implemented a similar but much 
more simple mechanism for doing the same thing in dkim-filter.  I've done 
some tests with very large headers and dkim-filter, and there's now a unit 
test to exercise the dstring stuff in libdkim's source code as well.  It 
all appears to be functional and not leaking.

If you're hitting this problem, please try the patch and let me know how 
it works.  The patch touches a large number of files; if you have trouble 
applying it for one reason or another, let me know and I can make a 
fresh tarball available privately.
