New Comment:
Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try avoid embedding huge scripts into the report.

Description:
------------
I continue to get a core dump using imp with imap from the horde
project.
The crash is reproducible but the gdb backtrace has changed after i've
inserted the debug code.
Also I think it's important to mention that if u substitute the
"var_dump()" code below with "print_r()" the crash disappear !!!
so we can switch this three cases:
case "code without debug": crash();
case "code with vardump($mime_part)": crash();
case "code with print_r($mime_part)": --> continue (but I can't still
see the page)
If I can help with something else please contact me, I' will keep a
copy of the code, also I can send U a tar.gz of all this stuff (may be
not usefull with my conf.)
