...and no error message anywhere !
Not even in the Apache error log? Not even a message about a segfault? Are you sure?
Also, you forgot to mention which OS you're using. That may also have to do with the observed phenomena.

Apache logs were the first place I searched ! But really nothing at all !
My server is a 2.4.22 Linux one, Apache 2.0.48 with
mod_ssl, mod_php (sorry !), mod_perl and mod_auth_pg.
All my scripts using GD have the same erratic behavior.
When started off-line, images are correctly generated but
not trough Apache invocation...

So it's a path problem (loading wrong library)?

I have had no problems using MP2 (ModPerl::Registry) and GD (well, Graph::Template, which uses GD::Graph which uses GD). I have a production site using it right now.
What sort of debugging have you done? Have you correctly set the content-type? That kind of stuff (if I remember correctly) changed slightly between MP1 and MP2 (well, Apache1 and Apache2, but same difference).

I have solved my problem by recompiling Apache without PHP and GD works now without trouble. So I think, it's effectivly a library path problem with the original gd library used by GD and an another one added by PHP install process (with gd support). Why does GD works correctly sometimes still a great mystery for me ... What kind of debugging could I try ?
I have only checked Apache logs.
Thanks all for your help (and for Graph::Template that I will try soon !)

To end with that, the problem is effectively a lib one. PHP module has is own libgd version which is used when configure is invoked with '--with-gd'. So, when a CGI Perl invokes GD, some strange things occures.
To avoid that without suppress PHP or PHP gd support, it's necessary to pass to configure '--with-gd=<path>' where <path> points to system directory where is the gd include directory and the libgd file. For me,
I've used '--with-gd=/usr'.
And no more strange things !
Thanks again
