This problem has been reoccurring periodically since around PHP 4.2.0 and continues to occur in 4.3.1. Unfortunately, the code that causes these errors to occur is quite large and attempts to create a small test case have been unsuccessful. Some examples of the corruption are provided below: Example 1: Script startup calling require_once(). /usr/local/apache/lariat/lariat2/find.php(14) : Fatal error - Cannot redeclare findup() (previously declared in ÈM@4:14) Example 2: Passing an array by value to a function. Array ( [0] => Ä 9 [Corrupted] [1] => DC [2] => 28 [3] => 334.87 [4] => Ä 9 [Corrupted] [5] => 0.00 [6] => 1825 ) PHP is running under Apache 1.3.27 and is compiled with the following options: ./configure \ --prefix=/usr/local/php_4.3.1 \ --with-apxs=/usr/local/apache/bin/apxs \ --enable-bcmath \ --enable-gd-native-ttf \ --with-gd \ --with-ttf \ --enable-calendar \ --with-mysql \ --enable-trans-sid \ --enable-inline-optimization \ --enable-track-vars \ --enable-versioning \ --with-openssl \ --with-iconv \ --enable-xml \ --with-pgsql=/usr/local/pgsql-7.3 \ --with-mcrypt \ --with-curl \ --with-zip \ --enable-ftp \ --with-zlib-dir=/usr \ --enable-debug Here is the backtrace: Program received signal SIGSEGV, Segmentation fault. 0x404053e0 in object.11 () from /usr/local/apache/libexec/libphp4.so.debug (gdb) bt #0 0x404053e0 in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #1 0x405382cc in php4_module () from /usr/local/apache/libexec/libphp4.so.debug #2 0x4040f93d in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #3 0x4041740a in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #4 0x4040f569 in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #5 0x4040540c in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #6 0x4040f93d in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #7 0x4041740a in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #8 0x4040f5b3 in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #9 0x4040540c in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #10 0x4040f93d in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #11 0x4041740a in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #12 0x4040f5b3 in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #13 0x4040540c in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #14 0x4040f93d in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #15 0x4041740a in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #16 0x4040f5b3 in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #17 0x4040540c in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #18 0x4040f93d in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #19 0x4041740a in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #20 0x40404ed7 in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #21 0x40410cd3 in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #22 0x403d4e5b in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #23 0x40429b48 in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #24 0x4042aa70 in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #25 0x4042aaef in object.11 () from /usr/local/apache/libexec/libphp4.so.debug #26 0x080554e9 in ap_invoke_handler () #27 0x0806b5df in process_request_internal () #28 0x0806b646 in ap_process_request () #29 0x08061e06 in child_main () #30 0x08061fe5 in make_child () #31 0x0806215c in startup_children () #32 0x080627ed in standalone_main () #33 0x0806307c in main () #34 0x4009214f in __libc_start_main () from /lib/libc.so.6 (gdb) Apache is linked to the following libraries: $ ldd /usr/local/apache/bin/httpd libm.so.6 => /lib/libm.so.6 (0x4001a000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x4003b000) libdb.so.2 => /lib/libdb.so.2 (0x40069000) libdl.so.2 => /lib/libdl.so.2 (0x40076000) libc.so.6 => /lib/libc.so.6 (0x40079000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) The PHP module is linked as follows: $ ldd /usr/local/apache/libexec/libphp4.so.debug libzzip-0.so.10 => /usr/local/lib/libzzip-0.so.10 (0x4031f000) libpq.so.2 => /usr/local/pgsql-7.3/lib/libpq.so.2 (0x40325000) libmcrypt.so.4 => /usr/lib/libmcrypt.so.4 (0x4033c000) libltdl.so.3 => /usr/lib/libltdl.so.3 (0x40342000) libpng.so.2 => /usr/lib/libpng.so.2 (0x40348000) libz.so.1 => /usr/lib/libz.so.1 (0x40373000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x40382000) libresolv.so.2 => /lib/libresolv.so.2 (0x403af000) libm.so.6 => /lib/libm.so.6 (0x403bf000) libdl.so.2 => /lib/libdl.so.2 (0x403e1000) libnsl.so.1 => /lib/libnsl.so.1 (0x403e4000) libcurl.so.2 => /usr/local/lib/libcurl.so.2 (0x403f8000) libc.so.6 => /lib/libc.so.6 (0x40415000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000) Please let me know if I can provide any other information to help isolate the cause of this problem.
