Hi team,

I am trying to migrate my SVN project to git, using simple git svn
clone command. The conversion stops at some revision with error:
 0 [main] perl 2287 cygwin_exception::open_stackdumpfile: Dumping
stack trace to perl.exe.stackdump

So, I tried to resume the migration using git svn fetch. It runs for
few minutes and again stops with the below error:
Svndiff data contains backward-sliding source view: Svndiff has
backwards-sliding source views at C:/Program
Files/Git/mingw64/share/perl5/Git/SVN/Ra.pm line 312.

I searched for the solution almost everywhere and tried every single
thing possible to solve this problem, but no luck.
I thought I would really get some help in solving this issue by
mailing the issue to you.

Thanks in advance!!
The response really matters .

Regards,
Chaya

That looks like an error thrown from the SVN libraries which
git-svn uses.  Perhaps contacting SVN developers can help,
since it's nothing I've seen before.

I also have no idea about the quality of libsvn, Perl, or
git-svn on cygwin or any Windows builds.  Would you happen to
have a Linux or *BSD machine to try "git svn clone" on?

Thanks
