#25956 [Opn->Bgs]: Apache: Illegal Instruction

ID: 25956 Updated by: iliaa@php.net Reported By: zefram at zefram dot net -Status: Open +Status: Bogus Bug Type: Reproducible crash Operating System: FreeBSD 4.9 STABLE PHP Version: 4.3.3 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Infitite function or method recursion will lead to stack overflow. Previous Comments: ------------------------------------------------------------------------ [2003-10-22 16:40:45] zefram at zefram dot net Figured out the cause and the fix. Still a nasty error that the compiler should look for, IMO. Here's the code that was broken: -------------- class Store extends Data { function showList($list_ref) { // Should be: $list = parent::showList($list_ref); $list = $this->showList($list_ref); return "a"; } } class Data { function showList($list_ref) { return ""; } } $test = new Store(); echo $test->showList(1); -------------- As you can see, infinite recursion is not your friend. John ------------------------------------------------------------------------ [2003-10-22 16:25:26] zefram at zefram dot net Description: ------------ Apache is killing children left and right giving this error: [Wed Oct 22 16:04:15 2003] [notice] child pid 1024 exit signal Illegal instruction (4) It happens every time I try to run an application I'm in the middle of building. Very frustrating. I cannot provide code, as it's a closed source app. I'll try to reduce the code to what's exactly dying, but I'm not sure at this point what it is. It seems to have to do with objects and perhaps inheritance. My compile options are: ./configure --with-apache=../apache_1.3.27/ --with-mysql --with-gd --enable-sockets --with-png-dir=/usr/include/ libpng --with-zlib-dir=/usr/include --with-jpeg-dir=/usr/ include/libjpeg -- with-mhash Apache just loads php4 and enables mod_rewrite. Apache is not dropping a core file, so I can't provide a backtrace. Any guidance would be much appreciated.
