I have an IRIX n32 problem with similar symptoms. IRIX -64 works fine.
I extended Mr. Tucker's changes to bntest.c to also demonstrate the
IRIX problem.
Replace Mr. Tucker's test_bn2dec with:
int test_bn2dec(BIO *bp, BN_CTX *ctx)
{
BIGNUM *a;
char buf[1024], *buf2;
BN_LONG bnlong;
a = BN_new();
for (bnlong = -1000; bnlong < 1000 ; bnlong++) {
sprintf(buf, "%d", (int) bnlong);
BN_dec2bn(&a, buf);
buf2 = BN_bn2dec(a);
if (strcmp(buf, buf2) != 0) {
fprintf(stderr,"bn2dec failed: '%s'
'%s'!\n",buf,buf2);
OPENSSL_free(buf2);
return 0;
}
OPENSSL_free(buf2);
}
BN_free(a);
a = BN_new();
/* these gyrations attempt to test an particular corner case w/o */
/* breaking every other architecture */
for ( bnlong=1; bnlong <= 10000000000000000000ULL; bnlong+=bnlong) {
sprintf(buf, BN_DEC_FMT1, bnlong);
BN_dec2bn(&a, buf);
buf2 = BN_bn2dec(a);
if (strcmp(buf, buf2) != 0) {
fprintf(stderr,"bn2dec failed: '%s'
'%s'!\n",buf,buf2);
OPENSSL_free(buf2);
return 0;
}
OPENSSL_free(buf2);
}
BN_free(a);
return 1;
}
When compiled -n32 -mips3 and run on an IRIX system which supports it
I get:
