After the patch there is no crash anymore, just seeing garbage. Before it was
crashing when I did
vim -c 'AuDidd rev1 1 rev2 tip **'
while current directory is inside aurum repository. The simplest way I know is
to do
mkdir test && cd test
hg clone https://bitbucket.org/ZyX_I/frawor
hg clone https://bitbucket.org/ZyX_I/aurum
vim -u /dev/null -N --cmd 'let &rtp=getcwd()."/frawor,".getcwd()."/aurum"' \
-c 'cd aurum' \
-c 'AuDiff rev1 1 rev2 tip **'
I have no idea why initial "longfilenamebug.vim" file is not crashing: STRCPY
that I replaced with STRNCPY must overwrite something in both cases (and in
that file filename is much longer). Now if you do ":file" after this you will
see garbage at the end.
I found another issue though: "python anything_that_throws_exception" is a
crash. I don't think it is related, will explore this now.
