[ts-gen] SIGSEGV on 32-bit jaunty, shim-090807

Mon Aug 24 14:58:51 EDT 2009

Thank you, Russ, for that sanity check...  ...there are so many
possible causes, but I will definitely follow your suggestions in the
next few days and see if I can narrow down possibilities.  I will post
my findings.

I really appreciate your taking the time to give me some thoughtful
ideas on where to look.

(On a side note, I am glad to see that the CentOS crisis a few weeks
ago seems to have been resolved!)
