How to report tree-ssa bugs (and an example)

[Gerald Pfeifer <gerald at pfeifer dot com>]

Where/how should we best report tree-ssa branch bugs?

And in case you're interested, please find one below, which triggers
if and only of -O3 is used; that seems to be an inliner issue?

% cat x.cc
enum WCType { WCfree, WCnone };

static bool checkWC(WCType requested) {
    static WCType state=WCfree;

    if (state==WCfree)
        state=requested;

    return state==requested;
    }

int main() {
    checkWC(WCnone);
    return checkWC(WCnone);
    }

% gccvs x.cc -O3
