Hi, svn blame and svn log show that this change came from a patch for 64bit support in PoDoFo:
_svn log -r 1005 PdfInputDevice.cpp
------------------------------------------------------------------------
r1005 | domseichter | 2009-04-03 20:36:41 +0200 (Fri, 03 Apr 2009) | 15 lines
Commited a large patch contributed by Ian Currington, which makes PoDoFo 64bit
safe. He was able to edit a 5GB PDF file in one test.
Citing from his email:
Today, after several months of development,
we are able to contribute a new set of changes to PoDoFo.
These are specifically about 64-bit porting. As you can imagine, the
changes are widespread, with data type changes.
To enable you do perform difference analysis, the changes are against
SVN 990. The changes dramatically reduce cast and data type warnings
on MS Visual Studio C++ x64. The changes have been tested internally
here on 4 or 5 machines, including Linux 32-bit, Linux 64-bit, and
Vista 64, Visual Studio 2008 x64.
I don't think that is the cause. I bet we would have other reports, if this
would cause general failures on Windows 7.
What kind of error do you get? Can you prepare a small testcase that shows an
exception along with a test file?
Cheers,
Dominik
