I have attached a somewhat annotated assembler output for the
wo_prof_global_var.c test.
The test aborts in the second loop at i = 968.
In the first loop, malloc gives us p[968].b == 0x400050d4 or 2.00493336.
We add 1.0, convert it a fixed value of 3, and save it in p[968].a.
Then, in the second loop, we load p[968].a and convert it to a float
value of 3. We do a floating-point compare of this value with
p[968].b + 1.0 = 3.0049336, and the compare fails.

These should all be 4 on hppa2.0w-hp-hpux11.11. They should be 8 on
hppa64-hp-hpux11.11. Don't think the problem is here.
