Compiler: C for AIX version 5 (xlc_r)
Web serveur: IBM_HTTP_Server/1.3.6.2 Apache/1.3.7-dev (Unix)
PHP was compiled with this options:

$ ./configure --prefix=/usr/local/php4 \
	      --with-apxs=/local/src/bin/apxs \
	      --with-config-file-path=/usr/local/php4/lib \
	      --with-mysql=/usr/local \
	      --with-exec-dir=/usr/bin \
	      --enable-inline-optimization \
	      --enable-magic-quotes \
              --enable-track-vars \
              --enable-memory-limit \
              --enable-debugger \
              --enable-safe-mode \
              --enable-sigchild \
	      --with-system-regex

I have added this to main/php_config.h to correct some
compilation trouble about undefined functions and 
redefinitions:
#define HAVE_DLFCN_H 1
/* #define HAVE_ALLOCA 1 */
#define HAVE_INT_8_16_32 1

The module is loaded correctly by apache but when a php script is call the script return the result and the 
daemon crash with a segmentation fault (11).

This is the test script:
  phpinfo.php:
  <? phpinfo() ?>

This is the result of dbx when the script is requested:
  # dbx /usr/HTTPServer/bin/httpd
  Type 'help' for help.
  reading symbolic information ...warning: no source compiled with -g

  (dbx) run -f /babel/httpd-dev/conf/httpd.conf -X

  Segmentation fault in _efree at 0xd0dcc294 ($t1)
  0xd0dcc294 (_efree+0x1c) 80630008        lwz   r3,0x8(r3)
  (dbx) quit
  #

Did I need to use other compiler, or something to configure ? did the efree function is bugged under AIX ?

Thanks for help.

This is AIX specific, gcc compiles this fine, this bug will be fixed at some point in the future. Dup of 4630.

Exact, no more core dump when the module is compiled with gcc 2.95.3.

Thanks.

This should be fixed in PHP 4.0.6. Please try the
latest release candidate from:
