New Comment:
This looks suspiciously like a bad glibc installation:
#0 0x00000000 in ?? ()
#1 0x407f9cec in db_open () from /lib/libnss_db.so.2
I doubt there is a PHP or Apache bug here. Try a simple program
calling getprotobyname("tcp") to see if that segfaults; try it again
when linked against -ldb.

Yes, you're right. There is a Segmentation Violation:

Can you try with -X added to the flags passed to run in gdb, to try a
single-process startup.

Description:
------------
Apache simply fails to start after loading all modules, it seems it
exits after loading, probably following initialization phase of the
modules. No error neither at console nor log files. This happens
since Apache 2.0.48 + PHP 4.3.4 in this machine, but I succeeded
to start Apache 2.0.49 + PHP 4.3.6 in a different machine. Now
tried Apache 2.0.52 + PHP 4.3.9 and still doesn't work.
This is PHP configure:
./configure --with-apxs2=/usr/local/apache-server2/bin/apxs
--enable-ctype --with-gd --enable-gd-native-ttf
--with-jpeg-dir=/usr --with-png --with-gmp --with-pgsql
--enable-shmop --enable-memory-limit --enable-shared
--disable-debug --with-zlib=/usr --disable-cgi
--disable-path-info-check --enable-safe-mode --with-openssl
--with-bz2 --enable-calendar --enable-exif --enable-ftp
--enable-sockets --without-mysql
This are Apache modules:
Server version: Apache/2.0.52
Server built: Oct 25 2004 18:59:00
Server's Module Magic Number: 20020903:9
Architecture: 32-bit

-D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
-D APR_USE_SYSVSEM_SERIALIZE
-D APR_USE_PTHREAD_SERIALIZE
-D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
-D APR_HAS_OTHER_CHILD
-D AP_HAVE_RELIABLE_PIPED_LOGS
-D HTTPD_ROOT="/usr/local/apache-server2"
-D SUEXEC_BIN="/usr/local/apache-server2/bin/suexec"
-D DEFAULT_PIDLOG="logs/httpd.pid"

-D DEFAULT_LOCKFILE="logs/accept.lock"
-D DEFAULT_ERRORLOG="logs/error_log"
