ID: 16319 Updated by: bloodfang@web.de Reported By: bloodfang@web.de Status: Feedback Bug Type: Unknown/Other Function Operating System: RedHat 7.1 PHP Version: 4.1.2 New Comment: Alright, Apache 1.3.24 configure line: ./configure --without-execstrip --prefix=/usr/apache --enable-module=digest --enable-module=log_agent --enable-module=mime_magic --enable-module=usertrack --enable-module=expires --enable-module=so --enable-module=vhost_alias --enable-module=headers --enable-module=info --enable-module=log_referer --enable-module=rewrite And, guess what, now it works - Although I'm still left clueless; I recompiled Apache quite a few times - the only difference here is --without-execstrip and all modules statically (I compiled some modules dynamically before). But I'd still like to know what's going on (because I want to recompile an Apache suited for my needs, and not one with complete debug information and all static modules). Previous Comments: ------------------------------------------------------------------------ [2002-03-27 15:14:43] bloodfang@web.de Well, here's some kind of full backtrace - But as you can see there is no symbol table info. (gdb) run -X Starting program: /usr/apache/bin/httpd -X Program received signal SIGSEGV, Segmentation fault. 0x08091045 in ap_base64decode_binary () at eval.c:41 41 eval.c: No such file or directory. in eval.c (gdb) bt full #0 0x08091045 in ap_base64decode_binary () at eval.c:41 ap = (void **) 0x811dd0f digval = 0 digval = 0 digval = 0 digval = 0 result = 135388431 result = 135388431 value = (void *) 0x811e001 #1 0xfffff510 in ?? () No symbol table info available. Cannot access memory at address 0xffffa882 I guess I'm going to compile Apache --without-execstrip after submitting this - maybe this can produce more info. ------------------------------------------------------------------------ [2002-03-27 15:05:26] mfischer@php.net ap_*() function prefixed do actually come from Apache itself. Good chance PHP even isn't involved there. Have you tried updating/recompiling your apache? Can you provide a full backtrace (bt full) ? ------------------------------------------------------------------------ [2002-03-27 14:56:05] bloodfang@web.de I got a quite strange problem... Setup: Apache 1.3.24 (also tried with 1.3.23) and PHP 4.1.2 (also tried with latest SS php4-2002-03-27-0900), always built with APXS as libphp4 shared object. Configure line: --enable-debug --with-apxs=/usr/apache/bin/apxs (Yes, not much here, just to see if it works. Also tried --disable-xml) There is no problem when I load a script in the document root directory, which does some simple file read operations (phpinfo() works too). However, as soon as I try to access a subdirectory, like my phpMyAdmin in dbadmin or sqladmin (with http access control, config access control just works fine) I get a SegFault. Strange thing is, I even get this if there's just one 'touch'ed index.php with length zero in the directory. My backtrace: ----------------------------------------------------- (gdb) run -X Starting program: /usr/apache/bin/httpd -X Program received signal SIGSEGV, Segmentation fault. 0x08091045 in ap_base64decode_binary () at eval.c:41 41 eval.c: No such file or directory. in eval.c ----------------------------------------------------- I don't even know where that eval.c is - so I have no means to fix it myself in any way. Maybe it's just a big fault of mine I cannot see, but I have no clue what the problem is. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16319&edit=1
