I compiled version 2.3.4 on hp-ux 11i, with shared and
threads enabled, using Gnu c 3.3.3.
'make test' fails on all tests that use readline() and/or
readlines() and test_univnewlines fails with a memory
fault and core dump. All other tests pass that I expect
to pass.
If I hand modify pyconfig.h to comment out with
universal newline support and recompile (after a make
clean) then the readline(s) failures go away.
I have also compiled without thread support and got the
same failures as with using universal newlines.

On further investigation I got everything to compile the way I
think it should if I ommit optimization.

Closing. Hope that's what you wanted.

Sometimes bugs that go away when you turn off optimization
are real problems in Python code. But not very often --
and even less often on HP-UX :-/
