when they cause the destination to expand. To see how evil this is try this: #include <pem.h> main() { BIGNUM *bn = NULL; int i; bn = BN_new(); BN_hex2bn(&bn, "FFFFFFFF"); BN_add_word(bn, 1); printf("Value %s\n", BN_bn2hex(bn)); } This would typically fail before the patch. It also screws up if you comment out the BN_hex2bn line above or in any situation where BN_add_word() causes the number of BN_ULONGs in the result to change (try doubling the number of FFs).
