gcc 2.2.2 (at least this is the output from gcc -v) on a
SPARC 1+ with sunos 4.1.1

i don't read this newsgroup and don't have access to news right now,
so please forgive me if this is well-known and also please Cc a copy
of your reply to terry@santafe.edu


i have a piece of C code with a switch statement that switches on a
variable that is an enum type. gdb shows me that the value of the
variable is x but in the switch it goes to the case for y (there is a
case for x). this happens when i use -O and not when i don't. the
regular sun cc doesn't make the error (though i haven't tried it with
-O). 

to be more specific, the problem happens when i add -O to the
following gcc options and not without:

-g -Wall -Wshadow -Wpointer-arith -Wcast-qual -Wcast-align -Waggregate-return -ggdb 

i cut my program down to a mini example to try and reproduce the
problem in a small example, but the problem went away.

before i invest more time on this, i'd like to know if it is already a
known problem. if not, i'll do something to get you a small example.

regards & thanks,
terry jones.
