You may be looking at something getting clobbered, and somehow that
manifests itself on OpenSolaris but not on the other platform(s).
Perhaps that has to do with the way data structures are aligned,
endianness (are you on Sparc or Intel?) etc.
Perhaps set some breakpoints and see if the handler field is ever
intact and where it gets clobbered.
In the SUNWapch22 package on OpenSolaris 2008.11, httpd 2.2.9 is
stripped, so I can't do much with the debugger.
But when I build my own apache 2.2.9 with debugging symbols (configure
--with-included-apr --enable-maintainer-mode), I can't reproduce the
problem.
(And I think I have seen this same problem on amd64 Ubuntu, but I
still need to confirm that...)
