Hi
I see a memory leak in Vim-7.4.2275 which can be
reproduced by:
$ valgrind --leak-check=yes --num-callers=50 \
vim -u NONE -N \
-c 'sign define Sign text=x' \
-c 'exe "sign place 1 line=3 name=Sign buffer=" . bufnr("%")' \
-c 'echo getbufinfo()' \
-c q 2> log
And log file contains:

Running ":echo getbufinfo()" N times results in N blocks
being leaked.
Vim was configured with:
$ ./configure --with-features=huge --enable-gui=none
And EXITFREE was define in src/Makefile.
