AW: AW: Possible access violation in svn_client_copy

I'm sorry, I don't get the time for supplying a complete patch for this topic. I think it will be possible that I try to write a patch for this bug but I think I'm not able to set up a build environment for subversion as this seems to take quite some time using windows.

If you are interested, I could supply a patch without compiling or testing it.
Otherwise I would be looking forward to seeing this bug fixed in one of the next versions even if I found the workaround for my special application.

Please let me know if I should supply the patch even with these restrictions.

Best Regards, Michael

Thank you for tracing this.

I think you're right: the "if (SVN_CLIENT__HAS_LOG_MSG_FUNC(ctx)) {...}"
code branch should not enclose code that modifies action hash in a way
that the rest of the function needs. Instead, that code should happen
outside the 'if'.

Since you're already set up to test this easily, would you like to try
writing a patch? (see http://subversion.tigris.org/hacking.html#patches)

If not, don't worry about it. You did provide a reproduction program,
and someone else can take this if you don't have time. But it sounds
like you have all the knowledge needed here, so it would be great if you
could take it all the way to the finish line...

Let us know.

Thanks,
-Karl
