Extremely boring:

   passwd:         files
   shadow:         files
   group:          files

   hosts:          files dns
   networks:       files

   ethers:         files
   protocols:      files
   rpc:            files
   services:       files

   netgroups:      files

   netgroup:   files
   publickey:  files

Lots of things, but not with regards to libc and resolving, I think.  With
2.3.1-8, it seems I only get segfaults in programs linked with pthreads
and using coroutines (i.e. switching the stack pointer). (at least wget,
ping etc. seem to work fine).

If it's just not working for me then it might either be a very rare
error (coroutines are rare) or some bug in the programs in question.

Maybe you want to reclassify this bugreport, or close it, to see wether
other users suffer from the same problem.

If I find the time I'll try to remove patches from the debian package to
see wether a specific patch is causing this, or maybe compiler options or
some other esoteric setting.
