This is with current CVS of 1.0 branch (no changes since 1.0.0 that would
affect this query):

$ createdb crash
$ createlang plpgsql crash
$ psql -d crash -f lwpostgis.sql
...
$ psql -d crash -c "SELECT GeometryFromText('POINT(-106 40.67)', -1);"

Note also that my postgresql version (8.0.0) has been compiled with
the --enable-cassert flag, which forces pfree() to really release memory
thus making memory bugs more easily visible.

What architecture are you on ?
What postgis/postgresql version ?
I used gcc 3.4.3 for the build... problem could also be there,
a report of warnings you received at compile time would help.
