It turns out this was an error in our compatibility code for asprintf
(). We were doing something with va_list structures that Solaris
didn't like. I'm actually surprised that it worked on the UltraSparc
version of Solaris, but it has been for some time for us.

Anyway, I committed a fix at r9223 on the subversion trunk - it
should make tonight's nightly tarball for the trunk. I've also asked
the release managers for v1.0.2 to push the fix into that release.

Thanks for reporting the issue and for the account. Let me know if
you have any further problems.

Brian
