Old Status: Open

Bug Type: mcrypt related
Operating System: Linux
PHP Version: 4.1.0
New Comment:
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?
