--- Comment #2 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
I'm fine with disabling libsanitizer. Libsanitizer's GCC maintainer(s), whose
job it is to make sure it is documented, and either works or is automatically
disabled on major targets, should do it.

I have tried this with 4.8.3 r205675 and my newlib cross config with the
following options:
-m4 -mb|-ml -O2 -g -fbuilding-libgcc -fno-stack-protector -fpic
-fvisibility=hidden -frandom-seed=0

and some other minor variations, but could not reproduce it.
Kaz, could you please also try it in your config?

All my 4.8 cross compilers including 4.8.2 and 4.8.3 don't fail
with ccFujO37.out.  Maybe a host compiler's problem.
Iwamatsu-san, which host compiler did you use?
Perhaps SH native one?

Oleg and Kojima-san, thanks for your work.

Yes, I was building on SH native.
And I am using gcc 4.6.3 version in the host.

Iwamatsu-san, if you have some time, could you please try building GCC 4.9? 
I'm sorry, but I don't have the right setup at hand to do it myself at the
moment.

Also, please notice that the current GCC 4.8 branch has some known problems in
the SH parts (produces wrong code) -- I'm working on back porting some patches
from 4.9.

Sure. I will build gcc 4.9 soon. 
When I get result, I report this bug.

I see. 
I am looking forward to your backport patch!

Well, yes. gcc-4.8 builds fine on native sh4 these days so it appears to have
been fixed.

Full build log of gcc-4.8.4, including a successful run of the testsuite:

> http://buildd.debian-ports.org/status/fetch.php?pkg=gcc-4.8&arch=sh4&ver=4.8.4-1&stamp=1422178262

I think it's safe to close this bug.

PS: My new SSD is due to arrive to tomorrow. So I might have my sh4 up and
running tomorrow already, available for debugging.

Adrian
