@herd, can't see anything outright wrong here, any idea ? @kavol, could you try to build it with -O2 in place of -Os and tell us if it changes anything ? I guess if it would, we should ask toolchain guys what they think about it.
Doesn't an ICE have to be, by definition, a compiler bug? Sure, the app can work around it by changing the code that triggers it (if you can), but... I guess it could be bad RAM, broken ccache or distcc, or failing/corrupted disk... Not that he's using ccache/distcc.
(In reply to comment #5) > I guess it could be bad RAM, overnight memtest86+ did not reveal anything ... > broken ccache or distcc, or failing/corrupted > disk... oh well, it sounds "optimistic" :-( I've retried to rebuild it today, and magically it works now, so closing guys, thankyou for the attention and sorry for wasting your time on something which may be a hardware issue
