--- Comment #29 from Greg Chandler <chandleg at wizardsworks dot org> --- I tried recompiling the native again with the absolute minimum, with debugging to help try to track this down: ../configure \ --disable-analyzer \ --disable-bootstrap \ --disable-cet \ --disable-default-pie \ --disable-default-ssp \ --disable-fixincludes \ --disable-gcov \ --disable-libada \ --disable-libgomp \ --disable-libitm \ --disable-libquadmath \ --disable-libsanitizer \ --disable-libssp \ --disable-libstdcxx-pch \ --disable-libvtv \ --disable-lto \ --disable-multilib \ --disable-nls \ --disable-objc-gc \ --disable-systemtap \ --disable-werror \ --enable-languages=c,c++ \ --without-libatomic \ --without-libbacktrace \ --without-isl \ --without-zstd \ --with-system-zlib \ STAGE1_C{,XX}FLAGS="-O0 -g" \ --build=x86_64-slackware-linux \ --host=alpha-linux-gnu \ --target=alpha-linux-gnu \ --prefix=/usr \ --libdir=/usr/lib \ --mandir=/usr/man \ --infodir=/usr/info \ --enable-valgrind-annotations I've also added kernel debugging options to oops/panic on hung treads set at 60 seconds. It turns out valgrind supports about everything except for alpha so I can't actually use that... So all I can tell at this point is that it 99% seems like the gcc driver. It forks cc1, but it looks like it's either in a sleep state or some kind of wait. I can't get gdb to give me anything usable to get past that.... Does anyone have any suggestions at this point to help me get unstuck and moving again?
