ID: 14731 Updated by: limefest@NOSPAM.underworld.net Reported By: jt-news@thoestesen.dk Status: Open Bug Type: *Graphics related Operating System: FreeBSD 4.4 PHP Version: 4.1.0 New Comment: I get the same problem reported here. It doesn't break on all my images. Just certain ones (all taken with the same camera.) Apache logs: FATAL: emalloc(): Unable to allocate -2147483648 bytes System Info: Apache/1.3.22 (Unix) (Red-Hat/Linux) mod_ssl/2.8.5 OpenSSL/0.9.6b DAV/1.0.2 PHP/4.1.1 mod_perl/1.24_01 Previous Comments: ------------------------------------------------------------------------ [2002-02-11 23:01:37] cvig@raw-io.com I had it working ok when reading one file from a DC4800. Tried to open 10 in a row and I got the following error in the apache log file for each file: FATAL: emalloc(): Unable to allocate -2147483648 bytes FreeBSD 4.5, PHP 4.1.1 ------------------------------------------------------------------------ [2002-01-11 17:43:35] chrille@isa.dknet.dk I've been strugling with this issue for some time, also on FreeBSD 4.4-stable. The bug still exists in CVS as of today. I can also conform that removing TAG_JPEGQUAL and TAG_MACRO fixes the problem. ------------------------------------------------------------------------ [2001-12-28 07:26:12] jt-news@thoestesen.dk When calling read_exif_data with a picture taken with a Kodak DC240 it causes PHP to crash. (This error is probably related to bug #14026) It seems to be caused to the (mis-)reading of the thumbnail-info from the exif-tag. After changing the ext/exif.c and removing the cases TAG_JPEGQUAL and TAG_MACRO at line 760-779, the read_exif_data runs without any problems - But then (of course) it only read the data about the picture and not the thumbnail. To reproduce call read_exif_data with any photo taken with a Kodak DC240 Examplephoto http://thoestesen.dk/DCP_4030.JPG ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=14731&edit=1
