ID: 26796 User updated by: arjen at glas dot its dot tudelft dot nl Reported By: arjen at glas dot its dot tudelft dot nl -Status: Feedback +Status: Open Bug Type: SQLite related Operating System: Linux (gentoo 1.4) PHP Version: 5CVS-2004-01-05 (dev) New Comment:
I'm sorry, when compiling with debug-symbols (--enable-debug) it doesn't seem to happen... Perhaps you can use this extra bit of information: gcc = 3.3.2 glibc = 2.3.2 postgresql = 7.4.1 apache = 2.0.48 Even weirder, when I start apache2 -X, its opening two processes. The manager (I suppose) and one handler (I suppose). The manager process dies, the handler seems to survive (at least, the one with the higher pid and which is displayed in the ps xaufww output as the lower one). When I attach gdb to that process, it doesn't really do anything, but if I attach gdb to the top process, it tells me there is a segfault and I can get the above stacktrace again. If you have any clues in how to build a proper debuggable php, please let me know. My config.nice contains: CFLAGS='-march=athlon-tbird -O3 -pipe' \ CXXFLAGS='-march=athlon-tbird -O3 -pipe' \ CC='gcc' \ CXX='g++' \ './configure' \ '--with-apxs2=/usr/sbin/apxs2' \ '--with-zlib' \ '--with-mysql' \ '--with-pgsql' I'll check whether it works correctly without the parameters, but they shouldn't make any difference. Previous Comments: ------------------------------------------------------------------------ [2004-01-05 18:23:53] [EMAIL PROTECTED] Could you please compile PHP with debug symbols and try again. That would make the backtrace much more informative. ------------------------------------------------------------------------ [2004-01-05 13:05:27] arjen at glas dot its dot tudelft dot nl Description: ------------ I just did a default install of today's php-snapshot (php5-200401051230) in my apache2 and when a script came to its pg_connect, to open a postgresql connection, it segfaulted. When I tried to debug that in gdb I saw a few sqlite-functions being mentioned, so I disabled the sqlite-extension and my scripts work perfectly now. This issue was not there in php-5b3 and a snapshot of 22-12-2003 Actual result: -------------- Below is the backtrace I got from gdb, when loading a single threaded debug apache (apache2 -X) Program received signal SIGSEGV, Segmentation fault.
