           Summary: Problems with optimization (O3)
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: optimization
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: peter at peem dot als dot lbl dot gov
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

Enabling optimization at the O3 level breaks the build of the source file
s.C. gcc 3.3 has no problems compiling this code.

Environment:

How-To-Repeat:
source code s.C

struct Range {
    struct Error {};
    Range(T value): value_(value) {
	if (value>=high || value<low)
	    throw Error();
    }
    Range& operator=(Range &r) { this->value_ = r.value_; }
    Range& operator=(T value) { return *this = Range(value); }
    operator T() { return value_; }

    T value_;
};


extern double const low = -1.0, high = 1.0;
Range<double const&, low, high> val(0.0);

I can confirm this on the mainline (20030825).  It is caused by unit-at-a-time which is enabled at 
-O3.
Jan this is your problem.

A simpler example is:

The testcase no longer reproduces for me.  I fixed similar issue some time ago 
so I guess this got fixed as well.

I can reproduce it with the same example and the larger one still in the mainline 
(20030926 and 20030925).

I see, this fails again with latest snapshot but didn't with one two
weeks old nor the hammer branch.  I am investigating what broke.  Thanks
for verifying this!
