ID: 16836 Updated by: sniper@php.net Reported By: mac@w4b.at -Status: Open +Status: Feedback Bug Type: MySQL related Operating System: Linux debian/woody PHP Version: 4.2.0 New Comment: Please try this snapshot: http://snaps.php.net/php4-latest.tar.gz Previous Comments: ------------------------------------------------------------------------ [2002-04-26 15:46:43] mac@w4b.at Nope, has same effect :( How can I check that libdb2 is ok? Maybe some bug in that lib? BG MaC ------------------------------------------------------------------------ [2002-04-26 14:10:31] sniper@php.net Does PHP 4.1.2 work any better then? ------------------------------------------------------------------------ [2002-04-26 09:40:59] mac@w4b.at Dear Developers, thank you a lot for quick reply. I tried it using minimal configuration: ./configure --enable-debug --with-mysql --with-apxs=/usr/bin/apxs Apache is libthread linked. Libc is Version: 2.2.5-4 MySql lines from /etc/services: grep mysql /etc/services mysql 3306/tcp # MySQL mysql 3306/udp # MySQL I think myself that it is a lib problem, but I reinstalled all libs, made hardware check before writing this bug report :( All libs are from woody, apt installed. BR MaC ------------------------------------------------------------------------ [2002-04-26 09:26:56] mfischer@php.net Please provide the full configure line of PHP. Also can you paste the relevant lines of the /etc/services file containing mysql? Btw, which version of libc are you using exactly (use dpkg -s libc6|grep Version ) ? It looks like a problem with your system libraries, not related to php or mysql at all. ------------------------------------------------------------------------ [2002-04-26 09:10:38] mac@w4b.at Dear Sniper, yet PHP Apache does not crash on requesting phpinfo() but does if I try to make MySql connection. I took sources from download section at php.net (Apr.22) and the config you told me. strace tells me: open("/lib/libdb.so.3", O_RDONLY) = 5 read(5, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\300*\0"..., 1024) = 1024 fstat64(5, {st_mode=S_IFREG|0644, st_size=233488, ...}) = 0 old_mmap(NULL, 236572, PROT_READ|PROT_EXEC, MAP_PRIVATE, 5, 0) = 0x40411000 mprotect(0x4044a000, 3100, PROT_NONE) = 0 old_mmap(0x4044a000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED, 5, 0x38000) = 0x4044a000 close(5) = 0 munmap(0x4037e000, 22601) = 0 --- SIGSEGV (Segmentation fault) --- +++ killed by SIGSEGV +++ gdb shows: #0 0x00000000 in ??
