Sorry, I were wrong. I didn't know that there is /lib/i686 But, anyway, this problem exists with Sun jdk 1.3.1 and 1.4.0. Using of IBM jdk 1.3.1 solves problem. But there was no such problem on RH 7.2!
Even /lib/libc.so.6 has the dynamic symbol table (otherwise it would be useless), see readelf -s /lib/libc.so.6 or nm -D /lib/libc.so.6. The fact is that because of a bug get*ent_r@@GLIBC_2.1.2 functions are not exported (but e.g. get*ent_r@GLIBC_2.0 are). I've fixed this in: http://sources.redhat.com/ml/libc-hacker/2002-06/msg00008.html Will work on a 7.3 errata for this next week.
This was fixed in glibc-2.2.5-36.
