ICE

[Geert Uytterhoeven]

JFYI, I'm getting an ICE when doing a m68k allmodconfig on next-20120927:

fs/gfs2/rgrp.c: In function ‘try_rgrp_unlink’:
fs/gfs2/rgrp.c:1625: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

make[2]: *** [fs/gfs2/rgrp.o] Error 1

The offending line has:

struct gfs2_rbm rbm = { .rgd = rgd, .bi = rgd->rd_bits, .offset = 0 };

Smaller failing case:

#include <linux/gfs2_ondisk.h>
#include "glock.h"

static void try_rgrp_unlink(struct gfs2_rgrpd *rgd, u64
*last_unlinked, u64 skip)
{
        struct gfs2_rbm rbm = { .rgd = rgd, .bi = rgd->rd_bits, .offset = 0 };
        return;
}

Interestingly, it compiles fine if I replace "glock.h" by "incore.h"
(the former includes
the latter). If both are include (first incore.h), it also fails.

Yeah, I know it's an old compiler...

Ouch!

Would it help were I to rebuild my gcc-4.6 cross-compiler for you
on/targetting… I guess Ubuntu lucid?

Thanks for the offer, but I also have a 4.6.3 from Tony's collection.
