[svn-r1103] Purpose:
Bug fix
Problem:
This bug is coming up as a bus error on some machines
(fuga, spank) in the "fillval" test. At higher levels of
optimizations, H5detect gets rid of a statement which is to
be used in alignment tests. Because of this, SIGBUS is never
delivered, and the alignment constraints of the machine are
not recorded correctly by H5detect in H5Tinit.c.
Solution:
By preventing the optimizer from getting rid of the statement
to be used in the alignment tests, SIGBUS is delivered as
expected, and the alignment constraints of the machine are
recorded correctly.
Platform tested:
Irix6.5(fuga), HPUX10.20(spank), Solaris2.5(Kryten)
