Hi,
I ran into a problem that gcc make check stops after one case in
asan.exp, here is the dump information:
Executed ./sleep-before-dying-1.exe, status 1

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.
