Confirmed. We for example have
t.c:39: note: Build SLP failed: not grouped load _46 = *pix_1;
as we fail to detect groups for
_46 = *pix_1;
_49 = MEM[(unsigned char *)pix_1 + 1B];
_52 = MEM[(unsigned char *)pix_1 + 2B];
...
as the step is not integral. That is, this is a strided-load SLP group.
I am working on a patch for this. This is one reason why PR37021 is not
vectorized in the best possible way.

Mine. I can only reproduce this with -fdump-tree-all-all though, so I doubt
this is the original issue.

I get the same error, and merging revision 197165 from trunk into my
working-directory for gcc-4_8-branch revision 198253 did not fix the error on
my system.
This error occured during one of the stages while building gcc, revision
198065, checked out from svn://gcc.gnu.org/svn/gcc/branches/gcc-4_8-branch for
MinGW32, Windows 7 Pro 64-bit SP1.
The error also occurs with revisions 198027 and 198253 -- that is, the error
has been occuring with revisions for at least these past 7 days.
The error persists after I merged revision 197165 from trunk into my
working-directory for gcc-4_8-branch revision 198253.

That's expected as the issue I fixed on trunk was not present on the 4.8
branch. Which is why I didn't close this bug. But as I cannot reproduce
it I rely on others for investigation.
Can you please provide a backtrace from the crash?

> Can you please provide a backtrace from the crash?
I'll be happy to provide a backtrace from the crash. It will take a day or so,
as I'm such a novice that I don't yet know how to create a backtrace.
In the meantime, here's a new development: The build that crashed was launched
using
make BOOT_CFLAGS='-O' bootstrap
Thinking that I'd need to remove the BOOT_CFLAGS='-O' in order to create a
backtrace, I rebuilt using simply
make bootstrap
Only this time, the bootstrap built to successful completion -- no crash.
This used revision 198253 with no changes (that is, I'd first reverted from my
working-directory the revision 197165 merged from trunk).
Any tips for a novice on how to create a backtrace from the crashed build?

Alas, no success. gdb reports "No stack." after the crash. I'd used
make BOOT_CFLAGS='-g -O' bootstrap
I'm happy to help if I can. Any suggestions on what more I can do?

To be more complete, here's the entire set of commands that I entered, along
with the screen output (which is abbreviated for most of the build):
$ make BOOT_CFLAGS='-g -O' bootstrap
...(redacted)

If issue still exists please open new bug with testcase for reproducing.
