Description

Is it just me, or this JPEG file:

<http://farm2.static.flickr.com/1159/533197401_e0d2c40636_o.jpg>

causes exiv2 to crash and burn? I've just tried with version 0.14:

[hveravellir 12:33 ~/Downloads/exiv2-0.14/src] % ./exifprint /Users/
marco/Desktop/533197401_e0d2c40636_o.jpg

The issue is related to #513, but not triggered by a Sony Makernote tag here. The size limit chosen to fix #513 was too large, the result is an out-of-memory situation when exiv2 tries to read the tag (IFD1 tag 0x0000, size 1097101154).
