Zdenek,
I can't bootstrap the tuples branch on 64bit hosts because pass_ch is miscompiling stage2/ifcvt.o and stage2/df-scan.o. This causes a segmentation fault while compiling 32/libgcc/bid128_fma.o.
By disabling pass_ch I can get past that failure. Would you have time to check it out?
Thanks. Diego.
