It looks like it's a bug between cascade_filter_fn and the actual filter function lf_to_crlf_filter_fn that gets triggered when the output buffer is too small. In this particular case, *isize_p=378 and *osize_p=1 which causes cascade_filter_fn to feed the filter data which it can't process because it doesn't have anywhere to put it. I think that the function assumes that the output buffer is always large enough, but there are many indirections, so it might be an off-by-one. > > How to reproduce: > > git clone git@xxxxxxxxxx:pikelang/Pike.git > > git checkout -f 0e2080f838c6f0bc7d670ac7549676a353451dca^ > > git checkout -f 0e2080f838c6f0bc7d670ac7549676a353451dca > > The first two commands complete as expected, while the last hangs forever. > Performing the same with git 1.7.6.4 works as expected. > > The problematic file seems to be > /src/modules/_Crypto/rijndael_ecb_vt.txt which has the attributes: > text ident eol=crlf > > Thanks, > > -- > Henrik Grubbström grubba@xxxxxxxxxx > Roxen Internet Software AB grubba@xxxxxxxxx
