I don't know about that. I just screwed up the time zone when setting up
the system, and keep forgetting to fix it -- it acts as if it is set to
GMT; however, the timezone name indicates that you have not configured the
timezone on your system.
I submitted the bug because I thought it might be indicative of a larger
problem. IMO segfault == bug. And there is that tendency for bugs to live
together.

=================
Update:
Just thought to play with this a bit more and:
TZ="AAAAAAAAAAAAAAAAAAAAAAAAAA" ../pgsql7.3/bin/initdb <-- segfault
TZ="AAAAAAAAAAAAAAAAAAAAAAAAA" ../pgsql7.3/bin/initdb <-- initdb failed
TZ="AAAAAAAAAAAAAAAAAAAAAAAA" ../pgsql7.3/bin/initdb <-- works.
Looks like a simple buffer overrun.
