Yes, it shouldn't crash. I'll check it (after the vacations!).
Thank you.

This is not a PHP bug, but in libmcrypt. I reported this to the author of the library.
This is the C code I used for it:

#include <unistd.h>
#include <mcrypt.h>

void main (void)
{
    int res;

    res = mcrypt_module_is_block_algorithm ("gost", NULL);
}

This one works, the next does not (segfaults):

#include <unistd.h>
#include <mcrypt.h>

void main (void)
{
    int res;

    res = mcrypt_module_is_block_algorithm_mode ("gost", NULL);
}

regards,
Derick

I know what it is buggy script, but it not the justification for "Segmentation".

Your script work for me and print "false"

Hello,

your script is buggy, GOST, is not a mode, but an algorithm.
It indeed crashes with this code, but to me it seems like it is an libmcrypt problem.

If you use this:
<?
        if (mcrypt_module_is_block_algorithm(MCRYPT_GOST))
                echo "true\n";
        else
                echo "false\n";
?>

it works, but it returns true if it is NOT a block algorithm, which is a bug in the extension.
(mcrypt returns 1 if it is a block algorithm).

Can you confirm that it does not crash with the script I pasted?

Derick
