in thread length() returns wrong result - suspicious magic
I though DBI was missing a def for SQL_WCHAR but it turns out it is there. The code started out as code someone submitted to me to look into another issue so I've only modified some parts of it.
Setting $txt = $txt at the end of the loop makes no difference but setting $txt='' fixes it. If this confirms your suspicion could you explain why DBD::ODBC (which wrote to the scalar) might need to call SvSETMAGIC?
