Same issue using 7.2.14 on CentOS 7. Code and images work fine with PHP 5.4.16 but with PHP 7.2.14
exif text output is truncated so can't get GPS data. Can't extract thumbnails with
exif_thumbnail(). These things are critical for my application and will delay moving to PHP 7.
EXEC exiftool is slow. FYI, the vote system here gets an HTTP 500 error and fails.

exif_read_data does not read all EXIF information in certain JPEG files.
Sample JPG here, that has the problem:
https://www.tornado.se/piwigo/tools/sample.jpg
Using exif_read_data produces the following output of 'sample.jpg':
https://www.tornado.se/piwigo/tools/metadata.php
I.e. it is not complete (using print_r and var_dump). The apache server produces the followong
errors in error_log:

Using exif_read_data seems to 'cut' up to a certain point of the EXIF header. Specifically
I want to extract the DateTimeOriginal value, but php 7.2.11 isn't able to find the value.
Using jhead or exiftool fully decodes all the EXIF headers.

It seems this issue is still present in PHP 7.2.11, e.g. with the sample image provided in this

Thanks for the zip! I will try take a look if there is something obviously wrong in ext/exif.
Ps. I think the reason its fixed in newer versions is due to stas@ security fixes that could have
flipped the coin and actually make them work.

Sorry, they are no longer there. Try https://betatest.opajaap.nl/wp-content/wppa-depot/opajaap/phpbug.zip
this zip contains 5 of them.
FYI: Seems to be fixed in php 7.2.7
