Segmentation fault on big XML file input

[findus]

Hi!

I'm using exiftool to get the mime-type of files, and at the same time extract some exif-data from files that contain it.
I have discovered that I have a file that makes exiftool crash with a segmentation fault. It's a big XML-file in UTF-16LE encoding:

Some metadata: (produced using Cygwin)

Code Select Expand


$ file failfile.xml
failfile.xml: XML  document, Little-endian UTF-16 Unicode text, with CRLF line terminators

$ file -i failfile.xml
failfile.xml: application/xml; charset=utf-16le

$ ls -la failfile.xml
-rwx------+ 1 Findus Domain Users 131897984 Sep  7  2011 failfile.xml


When I try to run exiftool on the file (for example with the command "exiftool failfile.xml"), the result is a long processing time (like 2 minutes), a huge memory consumption (1.75GB), and a segmentation fault before any output has been produced.

If I convert the file to UTF-8, it still takes very long time, and uses very much memory, but I get a result, and the program exits clean.

If I test on a smaller (like, a few kB) file in UTF-16LE, exiftool works like a charm.

I am using exiftool 8.99 in cygwin on windows 7 (same problem when i run it outside cygwin).

I can supply the file if it would help, but it is quite big, so I'm not uploading it now according to instructions in:
