Comment (by robe):

 Yap this is definitely a heisenbug of some sort.  I think it is the NULL
 that causes the -1 SRID.   What was especially strange is I got it without
 changing your function and was on the first test.  Then the second call it
 complained about the SRID 102... not being registered in spatial_ref_sys.
 and each subsequent time complained about the SRID until I just got rid of
 your sqft from the equation.  So seems each call is taking a slightly
 different path.

 I have been able to crash on 8.3.7 but never on 8.3.0.
