Bug Type: Apache2 related
Operating System: HP-UX 11.00
PHP Version: 4.3.0
New Comment:
I confirm you that:
- httpd.conf is working fine without the directive
LoadModule php4_module etc.
- Apache2 has always be set to work with
User www
Group other
(with Group nobody, in HP-UX11 Apache simply does not work)
Thanks for the "bt full" hint, yesterday it was the firs time I used
gdb, so please forgive my newbie behaviour :)
I tried again with httpd -X, putting some breakpoints around the
critical points, i.e.:
- when the load_module() method is invoked to check the input values
- when the apr_dso_load() method is invoked to check the input values
- after the apr_dso_load() method is finished and the apr_pstrcat()
method is invoked to generate the output string, to check the return
conditions
The source code is available in Apache2 distribution inside
modules/mappers/mod_so.c
Here is what "bt full" returned after each step (sorry, once again it's
long):

Just noticed there's some HPUX related note in the httpd.conf about not
running it as 'nobody'..I guess you know this too?
------------------------------------------------------------------------
[2003-02-19 22:57:32] [EMAIL PROTECTED]
Simple 'bt full' output would have been enough.. :)
Anyway, does it do the same if you run it with 'httpd -X' ?
(provide that backtrace, and just the bt output)
(gdb) run -X
<crash?>
(gdb) bt full
(and to be absolutely sure this is php bug, I assume that apache works
fine without PHP in httpd.conf? :)

Here you are the trace I got with gdb (long).
My comments are highlighted with //
Hope this can help.
Apparently, the apr_filepath_merge() method invoked by load_module()
fails during the strlen() evaluation.
Very odd, also because the parameters with the module name and the
relative path for libphp4.so are correct until that point.
Here you have the gdb trace:
