Optimizer Bug in SysV 3.1 C Compiler

[Earl Chew]

Hello World,

There appears to be a bug in the optimizer of the System V/VME 3.1 C Compiler
(Rel 2.0). Compile the following with:

		cc -o foo foo.c

and it will print 1.0000. Compile with

		cc -O -o foo foo.c

and I get a bus error (core dumped). Can anyone help?

setvar(v, n)

double *v, n;

{
  *v = n;
}
