This commit (https://github.com/file/file/commit/bb421c437d406760fb9f70f49e2eb5c504528450#diff-5c8aa65000f916c2f4b5c29c808ea851) fixes the duplicate output for tga images. It looks like this issue does not appear in version 5.32 or later anymore. ------------------------------------------------------------------------ [2019-06-22 20:38:55] dev at jdoubleu dot de According to git the ext-fileinfo did not change between 7.2 and 7.3 (see https://github.com/php/php-src/compare/PHP-7.2/ext/fileinfo/fileinfo.c..PHP-7.3/). Running the script under 7.1 returns "application/octet-stream". This might be related to https://bugs.php.net/bug.php?id=67516 (and others). Libmagic was updated from version 531 (PHP7.2) to 533 (PHP7.3). ------------------------------------------------------------------------ [2019-06-21 13:10:23] dev at jdoubleu dot de I have uploaded the images to Docker Hub: https://hub.docker.com/r/jdoubleu/php-bug-78183 Running the script in Travis CI also confirms this bug: https://travis-ci.com/jdoubleu/php-bug-78183/builds/116430262#L236 ------------------------------------------------------------------------ [2019-06-21 06:28:01] krakjoe@php.net Ah, I still had this page open from yesterday, and saw your comment after I posted analysis.
