nscd and getxxxxx_r () in glibc 2.1.2 are all screwed up. hstcache.c in nscd has: while (__gethostbyname2_r (key, AF_INET, &resultbuf, buffer, buflen, &hst, &h_errno) != 0 && h_errno == NETDB_INTERNAL && errno == ERANGE) { errno = 0; buflen += 256; buffer = alloca (buflen); } However, when getanswer_r in resolve/nss_dns/dns-host.c runs out of buffer around line 619, it never bothers to set errno nor h_errno. It does that with if (result->h_name == NULL) { .... } It is incorrect since getanswer_r can run out of memory after result->h_name is set. It looks like a mess to me. I hope someone will fix it soon. -- H.J. Lu (hjl@gnu.org)
