I can not reproduce this. Does this happen with that
example script included in this report?
Does this crash happen with specific images? Where could
I get those images? What was the configure line like
for configuring PHP ?

Hi Jani,
here is the backtrace of the second script:
Program received signal SIGSEGV, Segmentation fault.
0x40411786 in gd_module_entry () from /usr/local/apache/current/libexec/libphp4.so
(gdb) bt
#0 0x40411786 in gd_module_entry () from /usr/local/apache/current/libexec/libphp4.so
(gdb)
the script fails only if you call ImagePNG after the ImageCreateFromGD.
Also ImageGD2 creates corrupted files, but this is another bug ...
Regards,

I can't get your scripts to crash.
Could you please generate a GDB backtrace of the crash?

Sorry, my submitted PHP Version was wrong. I mean 4.0.7-dev from the latest CVS.
The script crash under cvs version.

I doubt that you could crash PHP by using functions
that don't exist..
Both imageGD2 and ImageCreateFromGD where added
AFTER PHP 4.0.6 was released. So they are only
available in the CVS.
And with the latest CVS version, both of your
scripts work just fine.
