Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip When compiling PHP make sure to built it with --enable-debug so that a detailed backtrace can be generated. Previous Comments: ------------------------------------------------------------------------ [2004-06-30 10:42:41] russell dot seymour at turtlesystems dot co dot uk Description: ------------ I have some photos in a MySQL database stored as BLOBS. I have some php code that pulls these blobs from the database and creates thumbnails on the fly. I am using imagecreatefromstring to do this. The strange thing is that I have 7 images and the third one works - none of the others do. However if I move the code and the database to another Apache/PHP system (this time using Solaris 9) everything works without modification. I have tried the fix in "Bug #24174: Seg. fault when calling imagecreatefromstring" but this has not worked.
