Hi,

   I have written a program that works normally without any optimization
   parameters, but gives incorrect results when any of the -OX optimizer
   option is used.  Is this a known bug in the compiler?  or do I have
   to program in a certain ways to get around the problem?

   GCC version: 2.7.2 / 2.7.2.1
   platform : SunOS 4.1.4 1 sun4m  / HP-UX B.10.01 A 9000/735
	      (tried on both machines)

   the program uses realloc to allocate memory for the data structures,
   and array of long integers to store 256bit bit vectors.
   free() is never used in the program.

   any help would be appreciated.
