I've noticed/fixed a few occurrences of doubled words like "the the",
"to to", etc. in other packages, so wrote this to find more of them:
git ls-files|xargs perl -0777 -n \
-e 'while (/\b(then?|if|but|or|and|to)\s+\1\b/gms)' \
-e '{$n=($` =~ tr/\n/\n/ + 1); ($v=$&)=~s/\n/\\n/g;' \
-e ' print "$ARGV:$n:$v\n"}' | grep -v ChangeLog
I would be inclined to prepare a patch if I thought it would
be applied (promptly?), but I submitted a clear/simple fix for
an obvious double-free bug (albeit only in a test case) a month ago:
http://patchwork.ozlabs.org/patch/85973/
avoid memory overrun in a test leading to potential double-free
* testsuite/test-expandargv.c (writeout_test): Fix off-by-one error:
i.e., do copy the trailing NUL byte.
AFAIK, it hasn't been applied. If a "real" bug has such low priority,
this is not a good time to submit a clean-up change.
Running the above command on gcc's master produced the following output:
Note that if you add "i" to the regexp match option list, you'll get
at least one more legitimate match:
gcc/fortran/gfortran.texi:970:The the
However, many of the mixed case matches are spurious.
(same for the "if if" matches in code)
