I found some unexpected time tonight. Sorry, but I cannot reproduce
your problem on Windows 2000. Under Cygwin 1.3.19-1 and 1.3.20-1,
PostgreSQL 7.3.1-1 successfully ran the entire regression test (i.e.,
make installcheck) without any stackdumps.

My WAG is something specific to your setup (e.g., XP, Cygwin
configuration, etc.) is tickling a bug.

Well, debugging under Cygwin (on any Windows OS) is pretty much the same
as anywhere else the GNU tools run. If you want to roll up your sleeves
and debug, then:

1. download the PostgreSQL 7.3.1-1 source from any Cygwin mirror

2. configure --enable-debug --enable-multibyte --prefix=/usr --sysconfdir=/etc

3. make

4. cp postgresql-7.3.1-1/src/backend/postgres.exe /usr/bin

5. gdb -nw postmaster

6. run -D /usr/share/postgresql/data (in gdb)

7. psql template1 (in another window)

8. investigate SEGV (in gdb)

Good Luck,
Jason
