	Dear Hal,

Many thanks for the tar files.
I made two tests :
+ I downloaded V1R2M2_base_4.7.2-files.tar.gz (as you mentioned even if our 
driver is  V1R2M1) in the directory /bglocal/cn/pub/gcc/.
I type this :
$ export LD_LIBRARY_PATH=/bglocal/cn/pub/gcc/V1R2M2_base_4.7.2/gnu-
linux-4.7.2/powerpc64-bgq-linux/lib:$LD_LIBRARY_PATH
$ /bgsys/drivers/ppcfloor/gnu-linux/powerpc64-bgq-linux/bin/ldd 
/bglocal/fe/pub/Clang/r217688-20140912/r217688-20140912/libc++/lib/libc++.so
Erreur de segmentation (core dumped)

It is perhaps normal because I try to use ldd command of the driver V1R2M1 
with libraries for V1R2M2.

+ So I downloaded  http://www.mcs.anl.gov/~hfinkel/bgclang/V1R2M1_base_4.7.2-
files.tar.gz in the directory /bglocal/cn/pub/gcc/. I tried this :

$ export LD_LIBRARY_PATH=/bglocal/cn/pub/gcc/V1R2M1_base_4.7.2/gnu-
linux-4.7.2/powerpc64-bgq-linux/lib:$LD_LIBRARY_PATH

/bglocal/fe/pub/Clang/r217688-20140912/r217688-20140912/libc++/lib/libc++.so

        libm.so.6 => /bglocal/cn/pub/gcc/V1R2M1_base_4.7.2/gnu-

        librt.so.1 => /bglocal/cn/pub/gcc/V1R2M1_base_4.7.2/gnu-

        /bgsys/drivers/ppcfloor/gnu-linux/powerpc64-bgq-linux/lib/ld64.so.1 
(0x00000000335b0000)
        libgcc_s.so.1 => /bglocal/cn/pub/gcc/V1R2M1_base_4.7.2/gnu-
linux-4.7.2/powerpc64-bgq-linux/lib/libgcc_s.so.1 (0x00000fffb4580000)

So the result is the same with a personal compiled version of gcc 4.7.2.

I think the problem comes from the tar files of r217688-20140912 which need 
glibc 2.17 and not from the toolchain of V1R2M1 driver with gcc 4.7.2. What do 
you think ?

I don't know if my explanations are clear. Let me know if not. 
Thank you in advance.
Best regards.
