[Bug c++/25014] New: seems to be a bug in optimization on sparc systems.

The following bug occurs only if -O (or higher optimization) is switched on.
I did not find out which of the single optimization switches is responsible for
it. The complete if statement is true, although none of each boolean value is
true. If I replace the enum variable "Type" by an int, the code works correct
even with optimization. Please let me know if this bug is already known or even

../configure --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin/ld --disable-nls
Thread model: posix
gcc version 3.4.1

System (uname -a)

//gcc -O   enumtest.cpp    (has the bug)
//gcc -O    enumtest.cpp  -lsupc++ (has the bug) 
//or: gcc    enumtest.cpp  -lsupc++ (is correct)
//output is(if used -O ): 

//output is(if not used -O ): 
//(as I expect)

        e_Zero  = 0
,       e_One
,       e_Two
,       e_Three
,       e_Four

int main () {
        ETestType Type= e_Four;
        if( ( Type == e_One ) 
         || ( Type == e_Two    ) 
         || ( Type == e_Three   ) )
        return 0;
