With the following patches applied - 58832 - 58833 - 58883 - 58905 and LRA enabled by default, I am seeing the same segfault on git master with: "../configure --disable-multilib --enable-multiarch --enable-bootstrap --enable-languages=c,c++" but not with ./configure --disable-multilib --enable-multiarch --disable-bootstrap --enable-languages=c,c++ I wonder whether this is related to "[committed] Fix m68k bootstrap segfault with late-combine" for m68k. I will revert the late combine change and see if that helps.
