Re: Redirection "svn info -r HEAD"

Ok thanks for the input :) Sounds reasonable to suspect CRT linkage issues
since stdout/stderr I/O operations probably rely on the CRT behaving.
I'll see if a TortoiseSVN daily fixes the problem as soon as I get time.
But if that doesn't fix it, so I should file a bug with TortoiseSVN instead
then?

(Just out of curiosity, is there a particular set of bugs/mailinglist
messages about the root cause for those CRT linkage problems? (being a
developer I find it interesting to learn from other's linker/-age issues))
