Following up my own post here with some wierd findings...
While taking a look at this problem, I did the natural thing a compiled a
version with debugging symbols (adding --with-maintainer-mode to the above
configure command) and not having OPTIM set. I put the new debugging bin
in place and started the server with FancyIndexing on.
To my suprise, it worked flawlessly. No SIGBUS'es; truss and gdb both
showed httpd processes happily processing requests that failed before.
I recompiled a new httpd bin without debugging and with OPTIM=-O3, as
before. It began failing again... and one thing that I noticed about the
failures... is that it happened only when viewing directories that have
regular files in them. Directories that have only other directories in it
would be fine.
A binary compiled the "default" way (no maintainer-mode and OPTIM) works
fine.
Are gcc optimizations perhaps broken on Solaris 8? I'll try lesser degrees
of optimizations tomorrow (-O2, etc).
