make check stops after one case in asan.exp


Hi,
I ran into a problem that gcc make check stops after one case in
asan.exp, here is the dump information:

ERROR: (DejaGnu) proc "lreverse {{ASAN_OPTIONS 0}}" does not exist.
The error code is CHILDSTATUS 30519 1
The info on the error is:
child process exited abnormally
    while executing
"close file8"

make check just exists after this error and I can only get partial
test results like:

		=== g++ Summary ===

# of expected passes		192
# of unsupported tests		9

So anything I missed?  Thanks very much.

The gcc is configured with :
../gcc/configure
       --prefix=/home/.../target/
       --with-gmp=/home/.../usr/
       --with-mpfr=/home/.../usr/
       --with-mpc=/home/.../usr/
       --with-ppl=/home/.../usr/
       --with-cloog=/home/.../usr/
       --with-host-libstdcxx='-static-libgcc
-Wl,-L/usr/lib/gcc/i486-linux-gnu/4.4.1/,-Bstatic,-lstdc++,-Bdynamic
-lm'
       --enable-languages=c,c++,lto

The triplet should be i686-pc-linux-gnu by default.

Best Regards.
