A library problem is plausible. anole builds without OpenSSL, and I have no
guess for which remaining library could be at fault. I could not reproduce
this in an HP-UX IA-64 build configured as follows (no HP compiler available):
./configure --enable-debug --enable-cassert --enable-depend --without-readline --without-zlib CC='gcc -pthread -mlp64'

Sandeep, I suggest trying a build at commit 36e5247, the last REL9_4_STABLE
commit known good on anole. If that build fails, you'll know there's an
environmental problem, like a broken dependency library. If that build
succeeds, please use "git bisect" to find which commit broke things, and
report the commit hash here.

Thanks,
