Hi all,
I would like to propose a consideration for LFS to move towards the
GCC-4 branch as the default LFS build. There are issues, but none that
are really show-stoppers.
Well, there's currently three issues I'm wanting to see fixed/addressed
before considering a GCC-4 based release.
3) 'cfdisk -P t' segfaults on particular partition layouts (at least I'm
guessing it's dependent on partition layouts, as reproducing it appears
to be 'tricky' at best). I've tried working with Chris Beaker on this,
but we were unable to reliably trigger/fix the bug. Changing the
optimisation from -O2 to -O makes the problem go away. Compiling with
'-O -funit-at-a-time' triggers it again (and it's the only one of the
'-O2' level optimisation passes that does so). Compiling with '-O2
-fno-unit-at-a-time' still segfaults though. (1604).
Cheers,
Matt.
I confirmed that it does in fact have to do with the partition layout. I
originally had hda1,2,3.4 - hda1 was a Windows partition, hda2 and 3
linux, and hda4 swap. I removed hda1 (not like I use Windows anymore
anyway...) and recompiled util-linux (by the book - default compiler
settings). It segfaulted again. Then I removed hda4 and recompiled again
- it worked fine.
