Title: ERROR Use of uninitialized value in concatenation (.)
Post by: jnioche on April 11, 2014, 10:57:22 AM

Am getting the following error on the file attached with version 9.56 on Linux :

Use of uninitialized value in concatenation (.) or string at /usr/local/share/perl/5.14.2/Image/ExifTool.pm line 3787, <EXIFTOOL_FILE> chunk 2.
substr outside of string at /usr/local/share/perl/5.14.2/Image/ExifTool.pm line 3787, <EXIFTOOL_FILE> chunk 2.

Thanks!

Wow, nasty. I'll look into this and post back when I know more.

Thanks for this report! It was a corrupted CanonCustom2 group that triggered the ExifTool bug. I will add an extra check and this bug will be fixed in ExifTool 9.57, which will return the following warnings for your image:
