Yes, it shouldn't crash. I'll check it (after the vacations!). Thank you. Previous Comments: ------------------------------------------------------------------------ [2001-12-25 11:41:06] derick@php.net 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 ------------------------------------------------------------------------ [2001-12-25 11:18:30] sitnikov@infonet.ee i use php-4.1.1 ------------------------------------------------------------------------ [2001-12-25 11:18:16] sitnikov@infonet.ee I know what it is buggy script, but it not the justification for "Segmentation". Your script work for me and print "false" ------------------------------------------------------------------------ [2001-12-25 11:09:03] derick@php.net 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?
