Subject: Problem in Vax C 2.2 Optimizer
Newsgroups: mod.computers.vax

I recently spent several frustrating days chasing down a problem
which appears to be due to a bug in the optimizer in Vax C 2.2.
I still don't know exactly what the problem is but it went
away by compiling with /NOOPT. Since the code I was working with
is so large and requires special hardware to run, I doubt DEC
will be able to use my code to find the problem. However, if you
start to notice strange errors occurring in your programs compiled
with 2.2 of Vax C, try /NOOPT.
