Without -g2 I have this error:
g[a+4>>2]=-$|0;
In function:
function Bg(a,b,$){a=a|0;b=b|0;$=+$;g[a>>2]=0.0;g[a+4>>2]=-$|0;return}
And SFE on roll-a-ball project still does not work with same error. I
start believe that I doing something wrong in build steps...
P.S. My projects have a lot of undefined symbols (but they does not
used), can this be a problem?
