I'm in the process of migrating from Fedora16 to Fedora17 (all
x86_64).  One of the last services that need to be migrated is pgpool.
 I've been successfully building & running version 3.2.1 on Fedora16
for a few months.  However, after rebuilding 3.2.1 on Fedora17, it
segfaults immediately after starting.  Here's a backtrace from the

Note if I use the 3.2.1 build from Fedora16 on Fedora17, it runs ok,
so this is something specific to building on Fedora17.  I'm not using
any non-default environment build variables.  My configure line is as
follows (this is from the RPM spec file that I'm using to handle the
build & packaging):
--with-pgsql=%{_libdir}/pgsql --disable-static --with-pam
--disable-rpath --sysconfdir=%{_sysconfdir}/%{short_name}/

Is this a known bug?
