This appears to be a generic MIPS problem, as it also occurs on our
SGI Iris 4D/240. I was hoping patch 15 would fix it, but it's still
there. On our box, the string returned by the eval in test 7 of
op.eval is getting stepped on somehow; compiling doio.c, eval.c, and
str.c without optimization (so dbx does something useful) doesn't help
the problem.

At a suggestion from beldar@mips.com (Gardner Cohen), I recompiled
without volatile. Everything works. Looks like the compiler is
generating bad code, even though it gives no errors.
