--- Comment #4 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > If stage1 fails, then it is not miscompilation of the compiler itself > (or it would be miscompilation by your system compiler instead). My bootstrap compiler is gcc version 5.0.0 20150107 (experimental) [trunk revision 219318] (GCC) I don't know which compiler FX is using (I guess Clang). > So no *.o bisection is needed. That said, I don't see what commit in that > range might be related. Candidates are 219970, 219973, 219974, and 219981.
