error build gcc (from cvs)

[Stian Skjelstad]

I have the lastets cvs of gcc, and are trying to make a crosscompiler:
host = i586-pc-linux-gnu
target = sparc64-linux-gnu

[my_wave@ludvig my_wave]$ gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-85)
[my_wave@ludvig my_wave]$ uname -a
Linux ludvig.lilo.no 2.4.12 #5 Mon Oct 15 17:20:30 CEST 2001 i586 unknown
[root@olebrum root]# ld -v
GNU ld version 2.11.90.0.8 (with BFD 2.11.90.0.8)
[my_wave@ludvig my_wave]$ /opt/bin/sparc64-linux-gnu-ld -v
GNU ld version 2.11.2 (with BFD 2.11.2)

gcc is configured with:

./configure --enable-shared --target=sparc64-linux-gnu --prefix=/opt/ 
--enable-languages=c,c++,objc


When I then run make cross, the build hangs at this point:

/home/my_wave/gcc3/build/gcc/xgcc -B/home/my_wave/gcc3/build/gcc/ 
-B/opt//sparc64-linux-gnu/bin/ -B/opt//sparc64-linux-gnu/lib/ -isystem

With a ps I see that /home/my_wave/gcc3/build/gcc/cc1 is running for about 5
hours, and I attached it with gdb and made a stack traceback:

after several next-step, it seems like it never is able to get out of this
block:

    ready=0x83a224c, n_ready=1) at ../../gcc/gcc/config/sparc/sparc.c:7992
